QuestionQUESTION: Hi Eric, I have a Carryall 294 4x4 with a Honda GX620 motor GCAD-2134319. It sat for about 2 years before I got it, I drained the gas tank the best I could with out removing it. replaced all the fluids and filters, spark plugs. I replaced the carburetor because I saw that they cut the solenoid wire, and the dealer wanted 103.95 for the solenoid, the carb was half the amount. It stared up great ran good for about 15-20 minutes, then it felt like it wasn't getting enough gas but it also smelt a little rich then it started backfiring though the exhaust. Tonight I replaced the the new gas filter because the new one had some stuff in it. It started but it wasn't idling smooth and when I took for a test ride, it started good then felt like it was starving for fuel and popping through the exhaust again.
Thanks for your help.
ANSWER: How old is the fuel you are using? Less than 30 days old?
Were there any plastic insulators, gaskets, or o-rings between the carburetor and engine?
Have you checked the valve clearances?
Let me know.

QUESTION: Hey Eric,
The gas is fresh 100% gas not ethanol blend, there is a spacer and 2 gaskets between the carb and the engine. No I haven't checked the valve clearances. The other thing I noticed is when it starts running really rough it doesn't want to engage the clutch to go forward you have to put it in reverse then back into forward to go, but that only happens when it sounds like its running out of gas.
Thanks
Burt
AnswerI would check those gaskets and the spacer. If the space is plastic I have seen these warp and leak when the engine warms up. Do you have a little Permatex II non-hardening to help seal the gaskets? It only takes a LITTLE bit...DO NOT use too much. I have used Permatex II non-hardening to help seal warped spacers. It is messy stuff...USE rubber gloves and DO NOT get any on your clothes.
Do you have feeler gauges to check the valve clearances?
Eric
