We have used the ru-vid.comUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!
Great maintenance video, allow me to also point out the little Port for the idle jet that is located just below it and the 3 fine holes on the inside next the tip of the air screw that also gets blocked sometimes 😎
@@kylewo0 The absolute quickest way it to remove it, plug all the openings, pour a gallon of muriatic acid through the fill, cap it slosh it around, flush it out really good, dry it, and you're done. Or if you don't want to remove it, fill it with metal rescue, let it sit, drain it and you're good. Metal Rescue is good on rust but not sludge, muriatic acid will clean everything.
@@TepcoCycleRepairhow bout preventing the issue again? Flush all gas in the tank before storing I assume? Even when starting every month or so? Yeah I might not remove that tank.. that box is a prison for that tank. But I will slosh and drain tank in place .. maybe shop vac the remain.
Wait!...no micro drill bits and drills like donnyboy and taryl??? You obviously need to be educated on how to properly fix surging🤦♂️😆. Nice job. One of the better explanations I’ve seen on YT. You actually talk about the low speed mixture screw. Everyone else brings out the power tools and start augering jets! IDIOTS! Well it has been getting me a lot of rework business in my shop!😆
Lol yeah drilling out jets is covering the issue. I always think of it like this, it ran good when new with the stock pilot jet, so now without intake or exhaust mods it's surging, why would you modify the pilot? Diagnose and fix the issue. Thanks for watching!
Does this happen on Economy mode cause mine’s doing this once I put it on regular mode it runs good just don’t like it when I set it on Economy and the surging begins up and down annoying noise. Will this help me
It may be surging due to a bad valve. I'm working on one now that has a bad intake valve (bent or carbon build up) and it will cause surging as well. See if you can get your hands on and do a leakdown test.
DO NOT BUY HONDA THEY DONT STAND BEHIND THIER PRODUCTS. I have a Honda 2200 its less then six months old. It started surging at and would not hold a idle. Brought it to a certified Honda dealer. They told me I need a new carb. It would cost $280 installed. I called Honda and was told fuel problems are not covered under warranty. It has 30 hours on the generator. The idle jet has a design problem and Honda knows it. There are RU-vid and blogs about it all over the internet. If you replace the jet with a updated aftermarket upgrade it fixes the problem. THERE NEEDS TO BE A CLASS ACTION LAWSUIT AGAINST HONDA.
I would put it out by the curb...just tell me where you live first..but seriously that stinks, I have noticed Honda quality has been dropping in there ATV line as well.
Thank you for this great video. Your step by step video made it really easy to fix a lemon of a used generator purchase. After watching your video, I was able to get my generator running like a champ. On behalf of my wife and I, THANK YOU!!!
Great video. I have a fleet of Honda bikes and motors and the most common issue is the idle jet blocked. Your tip on the tank filter is a gem. I'll change all my tank filters now. ! Many thanks.
Surging = Fuel Starvation, especially with less than half tank of fuel. A generator runs at high speeds all the time requiring the highest of volume of fuel in the line at all times. Generators are designed to be low profile and an inherent flaw is that the fuel tank is (TOO LOW) just slightly above the carb fuel inlet for gravity feed through a hose. At high speeds and especially with little fuel in the tank causes a weak flow to the fuel inlet causing starvation/surging. SOLUTION: I have a Honda GX-390 and have discovered that by raising the entire fuel tank by 8" gave me MUCH better fuel flow down to the carb and the surging went away even with almost no fuel left in the tank. You can definitely see the difference (before and after) with a see-thru clear fuel filter which should always be at least 1/2 full during operation on a high speed motor/generator. Another mistake I made was storing Ethanol fuel for more than one season in my shed. The stuff goes bad and causes havoc on small engines. Periodically check the color of the stored fuel in a glass jar. It should be clear. If it is golden/urine colored, DONT USE IT in a small engine.. Car engines don't seem to have a problem with the aged fuel. I had about 20 gallons of yellow colored fuel and added a few gallons at a time to an almost full tank of gas in my car and it burned it with no problem.
Thank you for your videos on this topic. This one, and the one you made to actually remove the carb off the engine helped me so much. I have used my eu3000 every day for the last 2 years and it hasnt failed me until today. It started surging and would cut off under medium to heavy loads. Thanks again for the tutorial.
Glad I watched this video before tearing into my Craftsman (Generac) 3000i. Was absolutely dreading having to "gut it like a fish" in order to get the carb off and clean the main jet and emulsion tube just as I have done on SO many motorcycle carbs. Remembered seeing the plastic idle screw on mine and wondered if I had the same pilot jet underneath. Sure enough! Had it out in a few minutes, and, sure enough IT WAS TOTALLY CLOGGED! Couple minutes later I had it back together, fired it up and runs like new! A BIG thank-you for saving me so much time and needless effort!!
Thanks so much for this great video. I was about to order separate parts, but got the petcock assembly instead. Pretty sure I can fix my surging issues now when I get the parts. 👏👏👏
I have a Predator 3500 and have had it for about 4 plus years so far. I am having a problem right now with mine. When I go to turn it off it keeps wanting to run and chug, and like it's dying but just won't shut off until all the gas in the carb runs out. Any advice?
TEPCO CYCLE REPAIR, GREAT VIDEO! I RECENTLY RAN TANK LOW, TOOK MY SMALL SHOP VAC TOP AND SUCKED OUT REMAINING FUEL, TANK DEBRIS AND MINOR RUST. AFTER THAT I SPRAYED BRAKE CLEAN ON PETCOCK FILTER, THEN PUT SHOP VAC TIP RIGHT OVER TO PULL CLEANER OUT. THAT HELPED ALOT! THEN I RAN ENGINE WITH FILTER OFF, AND DID SHORT BURST OF BRAKE CLEAN WITH ENGINE RUNNING, AFTER ENGINE STUMBLE THEN RPM RECOVERY I SHORT BURST AGAIN, I REPEATED THE PROCESS FOR A FEW MINUTES THE SURGE STOPPED. IT RAN GREAT AND SURGED STOPPED WHILE I WAS IN THERE I PUT IN A NEW SPARK PLUG AND OEM PAPER AIR FILTER, RE-OILED FOAM FILTER AS WELL PURRS LIKE A KITTEN! IM NOT SURE HOW OLD THIS HONDA EU300IS BUT I THINK IT IS AN EARLY VERISON DUE TO NOT HAVING THE CHARCOAL FUEL FUME FILTER THAT NEWER ONES HAVE (ACCORDING TO THE INTERNET. IT RUNS LIKE A TOP AND THESE ARE GREAT GENENRATORS! GREAT VIDEO ONCE AGAIN
I, of course, am not you - and my 'ways' sometimes differ. In my case, while not SPECIFICALLY dealing with the surging problem, it only makes a lit of sense to pull the emulsion tube and check the very tiny side holes. If enough junk has gotten to the idle jet then, to my way of thinking, the emulsion tube certainly should be checked and absolutely should be cleaned out if any of the side holes are blocked. Just common sense.
You're absolutely correct, if this was a carb clean video I would have done a thorough carb soak carb clean. I was going over common and usually overlooked issues (in tank filter).
Mine starts extremely hard in the cold weather. After that, like a Swiss watch. Changed carburetor with a genuine Honda part. Replaced air filter, cleaned spart arrester.
Great video... but clickbait title not appreciated. "For good" means.. permanently... but you knew that... which is the problem. There is nothing here that would keep this from happening again. Still a great vid.. Just hate clickbait. You are starting the conversation with a lie.. which is basically the middle finger. People are too nice. We need to call people out on this crap more often.
Great video! Another good thing to do is clean the main jet and emulsion tube. With bowl removed use a small slot screwdriver up the tube, unscrew, and jet with emulsion ntube will fall out. Clean and poke all holes with a wire. Also use ethanol fuel treatment and try to not use fuel with ethanol especially if not running it a lot.
We had a surge on our generac generator. We took the carb apart and cleaned it no change. Then we watched your video and we cleaned the pilot jet and it completely fixed the surge!!! Thanks for a great video!!
Cut a slot in it so you can turn it. Turn it in until it lightly seats then back it out 2 turns. Let it warm up and slowly turn it in and out until you get the highest idle. Turn a 1/4 turn at a time and let the idle settle. If you turn it and the idle starts to drop, turn it the other way. You should end up at a spot between 1.5-3 turns out from lightly seated.
Another potential cause is an air leak between the carb and the engine. I had this happen on a new Generac PM2200i. When I looked at the intake gasket, it was obvious that part of it had not been compressed. I applied a thin layer of Permatex gasket maker to the gasket, re-installed the carb and torqued it down and it runs great now.
I have had an issue with constant surging. I replced the carb and it still surges real bad. Now I think your suggestion may be something I should look into as I can'f figure out what it could be. The plastic jet is clean and open.
I was having surging issues with my rototiller. a Powermate. I took the carb apart and cleaned it, drained the gas tank, etc. Nothing worked until I pulled the pilot jet. I didn't have a pin or needle small enough to pass through, but poking it must've cleaned it out. I put it back together and it runs great. Thanks for the tip!!
Just put a new carb on got surge and doesn't want to run with out the choke it was a freebie that sat with old feul for a long time would bet my problem is the in tank feul filter because i tried to just drain the tank through it and barely got fuel so i just pulled the pitcock and drained it but dint clean the filter before reinstalling it so thanks for making me think about it .lol....
Fantastic! Can you show a detail of the throttle motor connection? I took mine apart and notice there is play between the stepper motor and the plastic plate on the throttle shaft. Seems like that would allow surging. My throttle does not snap closed..should it? Perhaps I'm missing a spring.
@@TepcoCycleRepair That's what I had done ! A local Ocala biker/ATV mech took carb out and throughly cleaned it inside and out and now generator 6500 runs stable ! At 3300rpm rather than I thought 3500rpm stock ? Just $85 tech fee. Wife wants to load 220amp (AC, lights and water heater) on it but I said NO way, just 110 stuff dear.
I disassembled the carb in my EU3000is for the first time, since it was new. There is no o-ring on the pilot jet, or in it's hole. I didn't see any remnants of there being one.
This may have been mentioned before but if you own a Honda 6500eu you must have your battery door on or it will surge. I was chasing the surge until I put the door on and instantly started to run correctly. The second cause would be as this video is doing.
Not necessarily, I just think the quality of the components are better. Metals, electrics etc. I've worked on a bunch of all brands and metal quality differs greatly and because of that things wear quicker, corrode faster and rubbers dry out faster in the less expensive units.
2:35 THANKYOU sir ! i got a generator, Honda EG3500 x. GXC 240 honda motor, surges. I redone the carb, thoroughly. Now, with this education, will clean that pilot jet. ...thanks again, from Alberta canada. oh, got a 7 hp Xstream 3100 gen, surges too. Both were sitting for years, in a barn. Will clear that carbs' jet, too. SHALOM, Mr cycle repair.
Thanks Brother! Well done - especially where you demonstrated a test to assess flow on the fuel filter. I am going to go fix mine right now. Previously - main jet clogged. Fixed that, got function. Now the idle lopes a bit and it does not perform great under full load. ... Going to clean the pin-hole then check the fuel filter. Living the dream.
WOW, What a nice surprise. I figured here we go, another goof drilling holes in the panels, air cleaner box or ripping the Charcoal Canister out. You are a great mechanic that knows what he's doing and a great teacher for sure. I have a Predator 3500 and can't believe all the bad advice out there. It's unreal and Harbor Freight along with those depending on their generator to keep warm or run their life support equipment pay the price. I did know about the pilot jet but still learned a couple of good points. Great job and am now Subscribed.
I just bought an EU2000I and it was not wanting to take a full load unless the choke was on. I cleaned the carb twice including the top jet and it will only run correctly with the choke half way on. It idles fine but is way lean at full throttle. I was able to get my money back but what is going on. Do these thing have a fuel pump of some sort. Float bowl appears to be full of fuel. It will run all day with the choke half on but it should run without it.
It's your pilot jet. Did you use a wire or something to push through it? Are the o-rings ok on the jet? Your description is a classic case of a clogged pilot jet.
I have an unrelated question to this video. I just replaced the gas tank on my generator. When I filled it full of gas, all of the gas drained out of the upper carb drain hose. Do you know why this would be? I don't see an adjustment screw.
Sounds like it's overflowing and filling the carburetor with fuel so check your float needle and make sure it's cutting the fuel off when the bowl is full.
It depends on the condition when taking it off. On the fuel valve definitely, where the carb mounted, I didn't it was good, any damage to it, replace it.
I had to take top fuel indicator off to fix float inside but when I screwed down indicator back on it seems to leak when moving around with full tank. Any recommendations on stopping gas from coming out around edges of the indicator?
If the rubber seal is dry or ripped, you can use something like a honda bond, or motoseal from permatex. Take it back out, clean and dry it good and apply as per the directions.
Very good video and nice explanation. I have predator 4000 and my problem is that it starts and runs fine on choke but when I slide it to run it shuts off. On choke I can run some tools that don't put too much load on it but If I put heavier load on it it will shut off too. Feels like fuel problem, can you help?
Hi, nice fix, btw is overload alarm on when it surges? Mine does, i dont know if the fuel problem or electrical. Goin to check it out in the morning. Thank you.
You took the bowl off but didnt show how to clean the main jet which will definitely cause surging too. Not sure why you would skip that. Everything else was spot on!
This was based on common overlooked things that can cause surging. Most people just clean the main jet and it still surges. Agreed though, should have at least mentioned it. I do have several other full carb clean videos in my carburetor playlist. Thanks for the input.
You missed cleaning the main jet and tube while the the bowl was off. There are a number of tiny holes on the length of the tube that become restricted. That been the issue many times in my experience.
I based this video on common overlook things that could cause surging. The tube you're talking about with the small holes is the emulsion tube the main jet usually has a much larger hole that I do see clogged at times but that usually completely stops it from running. I agree I should have at least mentioned it in this video. I do have several other videos covering the main jet and emultion tube. Thanks for the comment!
I took my 2000 EUi carb off to clean it, it needed it, the fuel bowl was all gunked up. I ultrasonically cleaned it and put it back together. It starts now but surges. Watching this video gave me a few tips on what to additionally check. Once I check those things and fix any problems I see I think it will be fixed.
Question. I noticed that when it surges with eco off and i pull the choke half way out it runs smooth. Can I run it like that and if not is it still the little jet?
Great video, thank you! Any recommendations on a product to flush gas lines? I'm trying to bring back this same generator from a 15 year storage with gas in it. I've drained the gas and done the basic maintenence items, but I'm sure the carb is caked in gum.
Just make sure all the ports are clear. Don't really need to soak it if you can get all the passages clear. I've cleaned tons by just pulling the pilot, drop the bowl, pull and clean the jets, blow cleaner through the ports and reassemble. Make sure the float needle and seat are clean as well.
Any advice on removing the petcock unit from the shut off valve shaft? Don’t want to break it and it’s a plastic to aluminum connection. Does it pull straight out or twist?
Great video. I have about 6700 hours on my EU3000IS (4 years old, CARB model) . About 1200 hours ago, it started running a little rough when ECO mode was off. But, during the winter, I never run the AC, so it stayed on ECO. About 300 hours ago, it really started getting rough. I previously cleaned the carburetor, but decided it may just be getting old. Purchased a new one, adjusted the valves, oil, air filter, spark arrestor. It seems to run a little better when I adjust the idle screw at one speed, but as soon as the load changes, it gets rough again. Now even at idle in ECO, it's running rough. Surges a lot. Anyways, I guess I should try the tank filter. Do you just unscrew from under the tank, or does it just pull out? I don't want to break it... Thanks again. Do you have a patreon or PayPal? I'm curious if it's just at the end of its life and the internals need to be replaced..
I have this SAME problem. I live off grid and eco mode would be nice to use because it saves so much gas. But it’s impossible to adjust because of the load changes.
Get it adjusted in eco mode with no load. It should be fine everywhere else in the rpm range. Always start with a good carb clean and valve lash check if you're having issues.
@@TepcoCycleRepair I dont think eco mode will work with my new inverter. When my batteries enter absorb charging mode it requires a heavier load. So the eco mode lags a little to long before it kicks on. Youll hear it rev up, but by that point my inverter already stopped the charging because it couldnt get the power fast enough. Then the inverter will stop the charging cycle, which in-turn unloads the generator. Then it restarts in bulk charging, and its a never ending cycle. maybe i could adjust the idle a little higher on the eco mode, never tried it yet. I think its just too much of a lag between calling for power, and revving up to that load.
Cleaned out the pilot jet as well as Sonic cleaning all carb parts. Still surging, though not as bad. As far as the mixture screw? What's the advantage of breaking off the tab to make it turn a full turn as opposed to just ¼ turn as it's intended ..... ESPECIALLY considering some genset carbs have no mixture screw adjustment at all - just a plug. I have 2 carbs for our Honda eu6500is. One came plugged (not adjustable) & the other is ¼ turn adjustable. But since some are obviously not intended to be adjusted, how crucial could cleaning out that port really be. I could remove the permanent plug if it were to really help.
Tepco Cycle Repair - our surge happens when eco is off - or a load of 3.5Kw's or greater demand is required while in eco mode. We have more maintenance & diagnostic hours of use, than actual generator need .... 37hrs vs 20 - total of 57hrs.
I have brand new honda 2200i. Been recalled, ran rough in economy mode before it was in shop,now slightly worse. Runs smoothly at half choke however. Hard to imagine anything clogged, can you suggest an adjustment? Thanks for the great video!
If it was repaired due to a recall, I would bring it back..if it needs choke to run, it's lean on the pilot, so pilot is clogged or it's sucking air somewhere.
@@TepcoCycleRepair Thanks for your response. I was hoping l wouldn't have to take it back, but its still under warranty. At least I'll sound like I know what's going on! Thanks again, great video!
