I'm repairing my Cag and just washed the frame. I took off the engine because I need a new air filter, pull start, exhaust pipe, and fuel filter. Besides those pieces of the engine how do I clean the engine, in and out?
Clean the outside with carb cleaner. and the inside if you chose to you should just need to clean the top of the piston and polish it with sand paper to get the carbon off and polish with 320 or 400 grit. remove the piston so you dont get any of the carbon or any of the sand paper in the motor and bearings
