Engine Spitting Fuel Through Intake

[rebeltaz]

If you can, disconnect the EGR hose start the engine and see if that makes the problem go away.

Hey... I was thinking. Before I put this back together... if that does fix the problem, what would the cause be? The only thing that I can think would be if compression was leaking past the rings. If that were the case, I shouldn't have such high compression (150psi), would I?

150 is about right.
I have a 1 cylinder 9 Horse engine with a spec of 176 psi.

Scrubcadet- Does the 9 horse have a lot of carbon in combustion area, including piston top ?

It can get in the crankcase through a worn exhaust valve guide.

Lol! That's the spec in the manual for the Kawasaki Fe 290
But I mis typed,it's 160.

10-4..

OK... so I put everything back together, disconnected the crankcase ventilation hose and started it back up. Still got the gas spraying out the intake and running way rich.

You've checked that the cam timing is correct, and that the compression release is working as it should?

I have checked the cam timing. There's a photo earlier in this thread that I took of that. The compression release, no... to look at that, I'm going to have to pull the camshaft out to see it. I did inject air into the cylinders, though, and I couldn't hear any leaks with the valves closed and the piston at top dead center.

I don't think that's a valid check of the compression release but I'm not familiar with your engine. There wouldn't be much point in a compression release still being open at TDC.
