I am considering to get a wideband to help me tune the carb, but your point about increasing the initial timing is interesting. I'm at around 15degrees initial and 36 Total.

Did you solve the run-on problem by increasing the initial advance or something else?

Thanks

If your plugs are wet try the bigger bushing and bump your full advance a bit. Pm me if you'd like to chat.
