Backfiring and missing

I have a simplicity legacy 25hp kohler when blowing snow this morning it was running fine. about 40mins into blowing it started missing and backfiring. Pulled into the garage checked fuel fitler plugs which looked lean and oil. Added some dry gas to the tank started up and let run for about 5 mins. Pulled outside and started PTO and ran fine. Started blowing snow and only was able to blow for about 3 mins and it started missing and backfiring again. Not sure what i need to look at next.

It may take as much as 60 PSI to overcome the fuel pressure regulator. No, you can't blow through it. I suspect you have a fuel starvation issue. It could be a clogged fuel filter. It may more likely be a pressure leak inside the tank. That pressure gauge you mentioned comes highly recommended at this point. There is a flexible line connecting the pump to the metal line in the tank. If it ruptures, you have only minimal pressure, and the vehicle starves for fuel. Using the gauge, turn the ignition on and off a couple of times, (do not start) If the filter is choked, you will still achieve pressure to overcome the regulator. If it never makes that much pressure, then it is the flex or the pump itself. My first experience with this I found the rupture after the third pump! Embarrassing!


If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

I had this problem too exept I have no clue what parts or blah b;ah blah. I just know that my coil pack was getting fried.burnt out because my wires were bad. The mechanic I went to was a moron because I took the car to him 3 times and he kept saying it was the coil ad kept replacing it. I took it to my uncle and he said my wires were in horrible shape and when this is the problem it fries your coil making your car run like a lawn mower! Well all i did was replace my wires and the car ran great! Well I hope this helped..

The heater just quit working. It worked fine yesterday but this morning it does not. The car is running a little hotter trhan normal but not overheating. Any ideas?


I would check to make sure the radiator is full and the overflow tank is filled to the proper level. It doesn't have to be very low for these cars to stop blowing heat.

Missing and backfiring during acceleration and climbing hills.


Could be vapor lock in the fuel system. Next time it does this, stop and try removing the fuel filler cap... Hope this helps...;-)

Engine misfire, only when it snows


Have you or the dealers checked the plug wires? Often when there is high humidty weak plug wires can cause the engine to miss and this is difficult to diagnose in a shop environment. Modern ignition systems have very high voltage and also worn plugs can cause the voltage to spike. This would let the weak plug wires lose the voltage and cause the engine to miss.
