Re: Water in magneto casing.
Alot of old timers use to use tranny fluid to clean out the intake and tops of cylinders and rev the **** outta the motor on cars, let me tell you it wasnt black smoke coming out the tail pipe it was pure white. My point is clean oil will burn white smoke. Maybe theres way too much oil in the mix here by accident or what ever and its fouling the plug. If it were me Id start with that kill switch and throw it away just for now to eliminate it as an issue its junk anyway. If I wasnt sure about the mix being accurate I would change that. HOW DID WATER GET INTO THAT MAG CASE? How does your spark plug look? Id go over all electrical connections to make sure their clean and connected.............
