Why is my atv Honda fourtrax 350 backfireing


it sounds like its starving for fuel, when it runs lean you will get backfires and if its running rough then it may be starving for fuel at idle. Try adjusting you mixture screw and see it the engine will smoot out. Your carb my be dirty and not allowing enough fuel through it.

I have a kohler 18 hp twin engine on a cub cadet. Backfire when shut off. Started back up sputtered. Fuel coming out by air filter. Took air filter off and ran great. What would be the problem?


Check to make sure idol isnt set too high, make sure the air filter is infact clean to prevent it from chocking itself, make sure choke is off :-) and also make sure you idol all the way down when you kill it. Make sure your spark plug is good to prevent flood, and detonation, peaceout.

Kohler backfires


This is a timing issue. Check the flywheel to make sure that it is not loose and that the woodruff key is still present.

Vanguard V Twin 18 hp. monted in Cushman Motor scooter, runs great at W.O.T and at on quarter throttle, misses at range inbetween


Sounds like your carb needs the fuel/air mix adjusted..uses all the gas at high speed but has excess at low speeds...find your adjusting screw and at med throttle slowly screw it clockwise until the engine starts to sputter then back it out until it starts to sputter again then continue to do this until you reach ideal mix where it runs the best it can..then go slowly through the throttle up and down..when set..unjust your idle speed screw to your ideal idle speed..if this dies not fix ..carb will bed cleaned or rebuilt. Good luck.. Note always push or pull your throttle handle slowly to position avoids gas load up causing sputter and backfire.

I have a Briggs and STatton 24 OHV intek motor on a craftsman lawn tractor. I got it on sale and when I got home it ran rough. The fuel line had collapsed or was plugged with some white powder. I took off...


It sounds like the fuel mixture is running very Lean..There are usually two adjusting screw screws on the carburettor that control the mixture. A Larger one is for the Main Jet and a smaller one for the Idle Jet. There is also an adjusting screw on the throttle butterfly to control the idle speed.
To adjust setup, start with at least a half tank of fuel, and have engine at operating tempurature (That is warm but not overly Hot). As a starting point, loosen (anticlockwise) Main Jet screw about half a turn, to richen mixture,so that engine will run without choke. Run engine at full speed and adjust main jet for highest smooth speed without engine missing due to mixture being too lean or rich.
Allow engine to idle and the adjust Idle Jet Screw for smoothest idle. Idle Speed screw may have to be adjusted if idle speed is too high/low.
Sequence above may have to be repeated to get best running. If engine hesitates sometime when sudden load is applied but then picks up, try adjusting Main Jet by 1/8 to 1/4 turn richer until it handles the load without faltering.
