Default Re: Exaust smoke coming out sprocket cover!!

Spray the crankshaft seals as well. If you are concerned about the carb cleaner damaging the coating on the magneto, or washing the grease off of the gears, you can also use a propane torch. Do NOT light the torch, just turn on the gas and hold the tip as close to the seal as you can. if there is a leak, the gas will be sucked in and alter the idling as well.
It also is way less messy.
EDIT: Have a CO2 fire extinguisher handy as well. Do not let Murphy get his chance to play his folly.
I personally hate Murphy's law..... :mad:
