Re: Gas in the crankcase?
You have two problems.
You forgot to turn the gas off (tip # 9) or the sediment bowl valve is bad, and you have a bad float, needle valve/seat or some trash causing it to stick.
If you have gas in the oil, drain it, add new oil & change the filter.
Then, make sure the sediment bowl valve works. With the gas turned off, remove the fuel line from the carb & put a bucket under it. If you find gas in the bucket after 24 hours, the valve is bad. If not, it was operator error! :) Turn the gas off.
You also have a sticking float or bad needle valve or seat in the carb.
This is one of the things that can happen if oil gets in the gas:
We just had an 8N in the shop that the owner wanted us to fix the carb leak and replace the starter because the engine wouldn"t turn over. Turns out the base had more gas in it than oil and the bearings didn"t get enough lube from the diluted oil and seized the engine. I think of that tractor every time I park my tractors now and don"t forget to shut the fuel off.
