Re: fuel in crankcase
If the fuel appears to be dripping out of the gasket between the cylinder and the exhaust pipe the I suspect that you have a split in the fuel pump diaphragm. This ties in with the cart not being used for a year so the diaphragm got brittle. The fuel then leaks past the diaphragm into the orifice to the crankcase and fills it up. You should be able to remove and dismantle the pump to inspect the diaphragm. If it is split the best solution will be to invest some $35 in a new pump.
