I do know to put the octane adjustment to 0 , but I'm a little fuzzy on the vacume thing. I just replaced the Vacume Advance and did the timming with the Vac line attached. It seems to run well but did I screw up?
I know you believe you understand what you think I said, but I'm not sure that you realize that what you heard is not what I meant!
