Found time to tear into the over heating problem I have been haveing with my 102.
Removed the right side inspection cover from the engine and was supprised to find nothing in the fins of the jug, and the fan blades on the flywheel looked nice and clean also. Next I ran some wire through the fins of the head and again nothing. SO I decided to check the carb to see how it was set, well wouldn't you know it the factory setting where still inplace on this new replacement carb. They where set good enough ti run the engine but where set way lean, I adjusted the low and high speed jets to where the engine ran smooth, than turned them out another 1/4 to 1/2 turn so as not to have a lean mixture. Hopefully this will solve the over heating problem, if not I will have to dig into the engine a little deaper, like maybe remove the head and check for carbon build up.
