Gas spits out exhaust - Stihl Saws

No, if it clears up after warming up it is just residual condensation in your exhaust system from the last time the car was driven. As a rule of thumb for your own information, every 6 gallons of gas burned creates approximately 1 gallon of condensation.

If you have not replaced plugs start there A bad map sensor will also cause black smoke and poor running

GASOLINE in the air filter is a serious fuel injection problem....to be honest....I have never heard of such a problem...air goes through the filter into the cylinder where it mixes with gas....to have gas spit back into the air filter.......exhaust valve stuck? Maybe intake manifold is leaking? Gas from the tank goes straight into the cylinder via the fuel injection hose...how does it get into the air filter is really a problem. .

Are you very sure its spitting out gas? If smoke is light in color, you have a blown head gasket-coolant level will drop and you can smell the odor of coolant in the air. If you're sure you have unburned fuel spitting out your exhaust, this is extremely dangerous to everyone around you so don't run it and get it to a shop or reply back to me...

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few .. let me know if u need help
thanks

i have a honda riding lawn mower but it will runn for a bit then quites

I know that you did not mention any overheating but have the cooling system checked for hydrocarbons or do a compression test (all cyls should be within 20% of each other. Even if you had one completely dead cylinder, it is very difficult for wet fuel to get through an exhaust system without vaporizing. Your symtoms sound very much like a partially failed head gasket.
I could be wrong, but without the benefit of being there, that's what it sounds like.

Since you have replaced all those parts already, I would suggest checking out the egr valve. Also I was wondering how the coilpacks or distributor are acting? Is the truck firing on all cylinders? Very possible you have leaky injector also.

Hello,
First confirm it is either gas or eastter. Wayer/condedste collects at the tail oip as a byproduct of the caralyctic converter on cold rngine It normally occurs on firts start of a cokd enginw. the ebgine idles low because it is col, but should reyutn to normsl after warm uo.. If for sure iys gasolinem and the engine runs eiygh, then angihector is bad, good luck. I hope this helped yyou
