Haven't been abvle to get my carb guy to look at it yet. But I've been searching on here and some other places. Timing was another item that I read could be part of the problem. I haven't been able to check my total timing yet cause my timing light doesn't have that capability. But my initial timing is like 6 or so. From what I've read these motors like about 10 or 12 generally. So I'm gonna play with that next chance I get, and try to get the total timing as well.
