I have a sport jet 90 and it started running rough and rich then it stop and could not be restarted. When we removed the spark plugs and motor the engine over, about a cup of fuel came out of the #3 cylinder. Has this happen to anyone out there?

Re: Gas in Cylinder

either the lower carb needle/seat is damaged or debris filled or the fuel pump diaphram let go.

Re: Gas in Cylinder

Thanks for a quick reply!
I had planned on a carburator rebuilt. However,I never consider the fuel pump. I guess it works off #3 cylinder vacumn/pressure? Also should I worry about fuel in the crank case ? Does the carb repair kit come with the main fuel needle? I was also told that I may have bent a rod trying to start the engine with a liquid lock.
