Generac IQ2000 Inverter Generator Troubleshooting & Repair(Also Craftsman) 

Well, thank you for that, I had the same problem with mine and fixed it with your video. My generator was tested for a couple minutes after I bought it, and then it sat unused for two-plus years. Then it would start just for a brief moment and die. And if I tried after that, it would crank without any sign of life until many hours later when a little fuel got past the blockage. I found some short-cuts to the procedure that some of your viewers might benefit from: Instead of pulling off the fuel line @11:50 , I cracked open the screw on the fuel bowl and looked for fuel in the drain line (the smaller clear tubing, not the pink-ish one). It told me the bowl did indeed have fuel, and it looked like clean gas. But, like yours, it doesn't tell you if fuel is getting further into the venturi. You can disconnect the 2-pin Molex connector to the fuel tank sending unit, and pull the gas tank off to one side (to the pull-start side) so it won't gravity feed the carb bowl. No need to pinch the hose. Plus, you can disconnect the black PCV line at the carb air intake elbow easier than from the valve cover side, which requires removing a clamp. It pulls right off. The wire I used to clean the jet was a RN60 resistor lead. It just barely fit, and measures 0.026" or about 0.66mm. The shroud fasteners are all 3mm hex. The selector knob is 2mm hex. And the carb and air filter are all 10mm nuts or bolts. I suppose if we disconnect the kill switch on the 3-way selector, then when we switch to the "off position," it would burn off the gas in the bowl before shutting itself down. This would be better for long term storage, but it also has some negative safety consequences if you leave it that way all the time. Too bad disconnecting the kill-switch requires so much time to pull off all the shrouds to get to those Molex connectors. Thanks again for posting this.My sp

Thanks for the video. The last part of the video, where you cleaned that blocked hole in the carburetor helped me. Helped turn on my PULSAR PG2000is.

Very good step by step trouble shooting - I always go for the carb bowl first, but I like the other steps noted - it seems 95% for me has been carb - Very good video.

Great video and thanks for all of the time, effort, and expense you put into the videos. Looking forward to the next video!

Very informative.

Could be but I have same one and my float bowl was shiny clean.Just a thought.

at 17:02 you highlighted a part that adjust the carb for economy,normal,turbo. What is the name of the part.Is it a stepper motor?

Excellent video. The content was very, very clean, concise, and exact. Now to clean my carb.

You showed ZERO about that black box on top of the carb

Nice video, very informative. I have an older model iX2000 which disassembles a little easier but the information you provided helped me get my generator up and running again. Thanks!

It must have been a Monday or Friday product. Some employee did not drain the bowl after pre-test. Thanks for the video. J K

You should add Craftsman 2200i to your title. I have been searching for days about how to put the carb back together and your video was perfect for me! Thanks!!

Great video, would have liked to see it run for a while and complete operational assessment, thanks for showing us what it took to get it to start

Your instructions worked for me. Cleaned out that little hole in the carb, and it purrs like a kitten! Thanks for the info

Hey you saved me a bunch of money getting me info and confidence to fix my unit.

Zombi clone sold by generac. 15 years ago genrerac made very good products .

Hey nice video. The small generators are nice. The problem is the electronics parts fail sometimes more often then the Honda model of this size. The electronics part cost like two thirds of the unit. This video tutorial was excellent

I bought this unit from a family member that worked there 5 years ago .. been sitting NIB in my garages in the three homes I've lived in since then .. tried to start it last week for the first time during a bird hunt and got nothing .. when I got home I discovered I literally had the EXACT same problem!! My bowl was a touch cleaner, but the exact same hole was clogged ..Cleaned out the exact same hole... Started right up!!! .. my edit .. a shirt cut to fuel switch troubleshoot .. open the carb bowl drain into a bottle, cycle the switch from run to off while fuel is draining, the fuel should stop draining when switch is off.

I drop the bowl instead of removing carb. I find 90% of fuel problems with fuel float valve clogged with FOD, rust, gummed fuel etc. Compressed air can clean jets but some carbs. have diaphams that could rupture by using too high air pressure from your air gun.

Pile of junk. Purchased less than a year ago and it leaks fuel when running. Called Generac for warranty work. Was given list of dealers, but either they do not work on portables or they quit working on Generac all together. This this is a fire hazard. I have given up on trying to get it repaired....I should have stayed with Honda!

Interesting video. I'm curious as to what the deal was from Orchard. Was it "as is, no returns" or would they have taken it back as initially defective?

Usually look for short videos but needed all the details you mentioned. Great video and well worth the time. Thanks for an awsome video.

Nice vid thanks, your comment about the fuel being left in their for so long sitting is something i have mentioned to my friends about the cars seen in walking dead they wont just start after 3 or 4 years just sitting there, and the fuel would be degraded.

I just ordered the IQ 3500. It's on back order. Thinking it might be newly assembled so won't have this starting problem of fuel sitting in the bowl for a long time?🤞 Don't know why the manufacturer doesn't put any stabil in after testing 🤔

Fantastic I think the Clarke inverter I picked up cheap is the same as this as it looks brand new

I just bought this generator in Costco in case i know how to fix it in the future thanks for the video :) I subscribed

I would be interested in it's life span . Honda who they copy run along time and have active idle control etc.

Many of these that are a little low on oil will start run 10 seconds and die. A common problem on construction sites. If nor level low oil sensor also shuts down .

Hi Doug. Outstanding troubleshooting .Has always I liked,Shared,added to Playlists. All my best.

What's the pink hose coming from the carb for? You moved it out of the way, but never commented on it.

Since you seem to be the only person knowledgeable ive found regarding this generator (if you even still own it) i have a question. Is the idle entirely controlled by the stepper motor? The actual cable is simply for choke. My iq2000 will not idle up when a load is applied, nor does idle change when adjusting the 3 pos rocker switch for standard, turbo, economy. Im leaning toward stepper motor as my little power indicator light up front is green and the unit is providing some electricity, though not much. I havent verified how many volts with a meter yet, but when hooled up to a window unit the generator doesnt shut down, the fan on the AC simply blows at a very low speed.

I have the same generator, while in use it turned off and never turned back on. The pull start is hard to pull, and still hard when the spark plug is removed. So, I am guessing the "generator" portion of the engine is the cause of the drag on the pull start. Is the issue serviceable? I have spark and oil, and spark plug looked normal for its use. Any suggestions? Thank you, great video BTW

Fantastic video! While attempting to get familiarize with my new generator, I wasn't able to pry apart the outer shell/ panels like you did to access the carburator despite removing all the screws located on both sides of the handle, all screws on the side panel where air filter and carburator is located, the bottom 3 Allen bolts on that same side, and all the perameter screws on the front control and back exhaust panel. What am I missing? My unit is of a different brand, but inside layout looks very similar to yours. I did not touch the smaller screws on the face of the control board, nor the bottom 3 Allen bolts located on opposite panel of the air filter. Is there something I need to loosen or unhook from the inside? Your help would be greatly appreciated!

Is there a trick for getting off the valve cover? I removed the nuts, but it refuses to come off?

great video! at first my IQ2000 would only run on choke, now it runs on run but it idles up and down constantly, what should i check?

Thanks for posting. Very informative. I definitely appreciate NOT including all the minutia of "interference" removal! Thank you. I need to do this same repair to mine I think. Left untreated gas in it for too long.

How do you regulate the choke? Mine turns on but when i try to move it to the run position it wants to turn off. The generator just keeps revving. Plz help

I have the same generator. When I use to try n start it. The lights would light up on Pulls. Now its not doing it and not starting. Any tips would help greatly.

The thing I needed most wasn't shown.....how to remove the cover to expose the fuel filter and carb ect.

A spark arrestor screen captures hot carbon deposits coming from the exhaust. It blocks the deposits from exiting the hot muffler and potentially igniting dry fuels. Dry fuels such as dead leaves, dry pine needles and dry grass. It's a requirement per the National Forestry Service. You will always have hot burning gasses inside a working muffler. Some mufflers also include a catalyst inside or catalytic converter. Makes small engines meet new stringent EPA requirements.

IQ 2000 is a good unit been around for quite some time. With the changes that have been made to the cosmetics when are they make them easier to start?

Thanks for the video

Clean mine. ,now it wont start ,,99.999% sure everything is the way I took it off

Generac IQ generator broken from the factory never had that problem with the Honda

Awesome

Great video, mine is also new but has been sitting 2 years, it will only run on choke.

A little shot of either would of made this process faster, also un hooking the fuel lines.

Ethanol gas will do that every time.

Mine only stays on on choke then turns off on run. What should I do?

FYI..That was no floor model.. It was a used model ..probably a return .. That unit was fueled up and used thats why you had the crud in the carb bowl.

At 17:01 the part you are pointing out is the throttle stepper motor. It is regulated by the engine controller in order to govern engine speed under different loads as well as varying speeds for economy an d normal modes.

You had to clean the carburetor on a brand new, never ran generator?! We have spark. I’m going to try a shot of starting fluid in the intake next. Could I just drop the bowl instead of removing the carburetor to clean the jet, etc?

Have any issues with it leaking oil? My Gp1200i runs great but seems to be leaking oil somewhere. Not necessarily a big deal but disappointing.

Gret video. I have an ix 2000. It runs and works mostly, when a load is put on it, it throttles up then when load is shut off it struggles to find idle again or may even die on eco or high idle. Any thoughts on how to fix this issue? Thanks.

Awesome video. Thank you.

😎👍🏼

I work on them to that had gas in bening from factory good job in the tutorial very well placed

My generator will pulse when it is started. It will rev up and idle down like a heartbeat. Whaty steps are needed to correct this problem? Any suggestions?

Late 80s and early 90s my dad bought generac generators for his construction business they would only last a couple of weeks before they quit generating electricity and he would exchange them for another one at payless cashway I think he said he went through 10 of them before he switched to another brand and those lasted for quite a few years!

This is EXACTLY what I was looking for! Step by step diagnosis. Thank you! Mine isn't even turning over....no put put put sound at all... This happened after it completely ran out of oil...woops. Any thoughts?

I like the way you presented this video 👍

I guessed it was a clogged carburetor. Just because it was never used, does not mean it never had gas that went bad. I would have simply used straight fuel cleaner, choke it fully and just try to start it until the cleaner starts to break the gunk.

I have a yamaha EF1000IS, every 7 days it would stop running due to fuel getting restricted going into the carby, turns out I had to remove the needle in the carby and blow out this crap that formed blocking the flow, this time i removed the fuel tank, turns out the filter thats meant to filter the fuel is not tight enough to make a seal letting the particles to just flow stopping just before the seat inlet, something so simple, you had one job yamaha and someone stuffed up installing an undersized filter in the tank.

We have had ours for over 2 years.. tried using it once but all the fuel leaked through the carburetor hoses

Do u know how to adjust the voltage. My country is 240v but it appear 260v in my voltage metre. Mine is senci genset inverter.

What is the pinkish hose supposed to be connected to? I bought this generator and both clear tubes from carb are loose and when I go to start it drains the gas from the loose pinkish hose.

I wanted the video and it helped me to understand how to put mine back together. What mine is doing is surging with no load. I watched it and it looks like the stepper is the source of the issue. Any advice? BTW mine is a Westinghouse igen 2500 but the guts look exactly the same.

Bowls should never be a rust-able metal and coated or plated to prevent corrosion because they last only a few years.

Took mine part to fix this same thing (thanks) fuel guage is not working, where does the guage wire go? Sould go into the front cover but cannot find where.

Wow you have a gift for teaching my friend. Thankyou sir.

Hi there. I have this unit. General iq2000. Will not start. Checked compression and I’m at 40 psi at best..... thoughts?? Thanks

First Comment

800 ? You Got Beat I paid 475 for a New Version from Amazon

Mine is extremely hard to start . I hate it . It was that way out of the box for me

Isnt that a Yamaha or clone engine Carby also?

Simple as that, a perfect example of why you should always use top grade premium fuel in all your power tools. Thanks for sharing, Cheers

Why did you blurr out the model number?

Hello, great video very informative. I got a new Westinghouse i gen 2500 ran last year for 15 min. I tried to start up this unit this year and no luck. I did everything you have suggested in your video ( almost similar parts) and all i hear is a sound that the engine want to start but it dies few seconds later. Do you have other suggestions? New oil, new fuel, carb clean up, check the spark plug, air filter etc.... Tks for replying. Have a great day.

Enjoyed the vider. One of the problems, which Honda has mitigated is the micro switch that shuts the engine off before the carburetor can burn off excess fuel. Honda has a shut off setting on the EU2200 where you can shut off the fuel flow before you shut down the generator so there is very little fuel left in the carb after shut down. In my Briggs and Stratton 2200 I disconnected the micro switch and installed a toggle switch for quick shut down for refueling. Otherwise I turn the fuel valve off and let it run the fuel out of the carb.
