I have a Snapper Yard Cruiser with a Kohler 15 hp OHV engine. Family no.SKH426U1G2RB; model cv15s; spec.no.41570. I bought this mower new and started having fuel troubles after about a year. My dealer rebuilt the carburetor but I started having the same trouble after a few weeks. I took my mower to another snapper dealer and they replaced the carburetor along with a lower engine gasket which started leaking oil because of the gas which kept leaking into the oil past the piston rings. Now my engine has developed the same troubles, plus this morning I see that I have a mix of oil and gas on my garage floor under my mower and no oil showing on the dipstick. I got a little ahead of myself. The trouble with my engine started with backfires then the engine wouldn't turn over because the cylinder filled with gas and I had to turn the flywheel or pull the sparkplug to get the gas out the cylinder to relive the pressure on the valves. Then when the engine did start it blew raw gas out of the exhaust. My question to you is what I can do to take care of the problem as I don't trust the carburetors for this engine. I can't believe I am the only one to experience this problem. Has Kohler ever had a recall due to this problem? Now with the oil on the floor would it be cheaper to get a new engine than to have this one repaired? The last time I had the carburetor and gasket replaced my bill was almost $500. Thank you for your time. Joe
