hi everyone, i am rebuilding my friends rm 250 from 1986 and it wont start! it has been ridden one time 2 months ago and when i want to start it now it spews out feul! now the spark plug works, the carb is clean and OK, and he has some very good compression, now after taking off the cilinder and stuff there was some black fluid in the crankshaft tranny i think its oil with a little bit of fuel in it. it isnt oil from the gearbox or water from the cooling system. just oil from the feul; the engine has flooded a time ago and i think its that feul from when it was flooded. could it be that the feul was evaporated and the oil just sank to the bottom of the engine? i have checked everyting in the carb and everything is fine now do i need to drain that feul from the crankshaft? and could it be fine after that? i am out of ideas... everything works fine exept that it spews out that black substance... realy weird
