Actually it's a problem with my 1980 Kawasaki Invader 440 Liquid (snowmobile) so not sure if this thread will be deleted but I thought someone might have some insight.
Put my sled away in the spring running great. Didn't drain the gas and next winter I have a crank case full of gas. Removed the pipes and carbs and then started the sled to let it run off the gas in the crank until most was burned out/off (yes it would start and run w/o carbs) .
Between the carbs and tank is a stand alone Mikuni fuel pump that runs off crank vacuum. Took pump apart and it looks great. Had a local shop check my float needles (checks them with a vacuum gage or some set up). He says they're fine. Not surprising they're only a few years old.
How can that fuel be making it into the crank??
Any suggestions or thoughts appreciated.
