Many thanks blake ive had issues with my carb leaking out fuel on my homelite jet washer for a couple of years, 1st time i stripped it i used gasket sealant and unknowingly obviously blocked the air bleed which you pointed out in your video, free'd it up and bingo its running fab now.. many thanks 👍
Bro never use a feeler gauge on a overhead valve on a Stihl blower still makes a tool specifically made for the valves i highly recommend u buy the tool..... sincerely RIGO SMALL ENGINE REPAIR
Having the same issue. Big headache. I adjusted the valves, I installed a new spark plug, new carburetor, new air filters, new fuel filters, new ignition coil, still doesn’t start. Only started once or twice for 10 seconds each time: what do you think it is ?
Thank you so much for including the air vent issue. I am about to try and figure out why the new carb I got for my neighbors mower is leaking gasoline and I would have been stumped if it doesn't end up being the needle seated improperly. Excellent info.
I have a Nikki carburetor but has shut off thing on th bottom of th cup can that be th same problem I'm having or is mine a different problem cause it has a different shut off
I knew right away what happened because it had happened to me before. But my bolt came out of the exhaust stuck to the fly wheel and wedged between the coil and fly wheel. It was like a freak accident but it happened. Not sure how to add a picture but I have a picture of it.
Seems odd to me with the way you went through your diagnostic. Going straight to the Cam really seems like a huge waste of time. Why not check for spark first, then compression test, look at the spark arrestor to make sure it's not clogged, follow up with some Carburetor cleaner ( NOT BRAKE CLEANER ) for one brake cleaner will wash down the cylinder of any oil residue, along with brake cleaner will ruin a lot of Orings , primer bulbs and the list goes on. Stay away from brake cleaner on all small engine equipment. Then I would have gone to the valves to see if it needed adjustment, followed up with the fly wheel. Im sure you have your own method of madness however seems like you started backwards. The easy stuff first is way faster. and knocks out a laundry list of potential issues fast. Anyway, great video to show the end result of the problem.
I've seen that key get sheared off before when a customer forgot to properly tighten the flywheel bolt and tried to start the engine. One good pull is all it takes if it is loose and suddenly your ignition timing is so far off it will never run.
Thanks for the suggestion of checking the vent hole on the carb. I have been frustrated with leaking fuel on a 2 stroke ATV. I can't tell you how many times I have removed the carb, checked the bowl, adjusted the movement of the bowl by bending the tabs, changed the needle and seat and just been resigned to shutting off the fuel at the tank when not running. I have gotten to the point where I purchased a new, China carb and will eventually do a swap, but the puzzle of the fuel leaking still challengers me to find a solution. Maybe the vent hole was the problem all along. Thanks.
If the machine idles ok but just won't rev it's not a compression issue. You normally notice compression problems at idle. Most engines providing you can get them started will rev fine but not idle if the compression is too low. Maybe remove the muffler and check the port isn't blocked, or if you have a donor machine try the coil to see if the rev limiter has gone bad. Muffler itself could be blocked inside.
Im dealing with a carb that was overflowing no matter what. I tested everything and found the float has gas in one of the sides. New one on order. Im hoping it solves the problem. Runs great otherwise. Plug shows rich condition.
Thank God thank you brother holy crap I was 40min away from taking a hit out on my generator. Couple hard pipe hitting ....to go to work on the homs with a pair of pliers and a blow torch....!
2:00 time. Soak that bowl, in vinegar overnight. Keep an eye out, for acidification on some types of metals ; some pot metals will be eaten up if left in vinegar too long. Works good, though ! Shiner right up. Sometimes, i use a small round wire brush on a drill, to clean this float bowl.....
I don't hear a squal, just the choke handle rattling around because it's not flipped securely into the disengaged position. Can you pinpoint the location the sound is coming from with a tube or pipe held to your ear?
Update: did some thinking after recording and opted to order a new piston ring. The cylinder walls don’t look too bad. Our ring end gap was 0.034” and generally you want 0.005”/inch of bore diameter so for us between 0.006-0.007” is an acceptable ring end gap. $10 ring and should be here in a week
