Im still trying to work out an over heating issue. Engine runs hot and I lose timing and get backfires through the carbs. And it will kick my leg back. My electronic advance is all the eay advanced to hit my timing mark. Ive seen it on a Utube video with out an answer why. I am also dealing with alumimum shavings in my oil which I ordered a new chain and guide. Is it possible that my chain is so wore out that is why I have to advance my timing so far? And it is causing my engine to heat?No, I don't think it would cause much extra heat, the advance rod doesn't move much. It will cause it to stick though, so it won't smoothly go from retarded to advanced and back again. This causes all sorts of running problems because the timing isn't matched to the engine speed as it should be.
