I had the engine running and it just died out after riding for a few. I tore the carb apart and cleaned it good with carb cleaner, put it back together the same way, made sure to count the needle turns and put them back the same turns. I've now noticed that when the fuel is turned on I have fuel coming out the crankshaft behind the clutch. I figure I have a bad crank seal. But is there a reason that gas pours out the crank shaft just by turning the fuel on. It doesn't seem right. Could I also have a carb issue. I'm not familiar with these engines at all. I just got a fox desert fox and this is the engine that was on it.
