well I fixed the advance mechanism , by the way thanks for suggesting it, back plate was getting it stuck open . now she runs pretty smooth . just no power and to the next issue . I know its a 1200 don't know what it has for pistons but I can kick start her real easy not much compression fires rite up , I have a fat boy pushing almost 100 horses .which it doesn't help it feels like the shovel doesn't move , still think she should have a little more . I can't get her to idle that well , when she's cold choke all open she fires rite up engine racing , when she warms up idle is too high so I lower it and seems ok . at the next stop light she wants to stall because idle is too low . played with mixture screw and get it to sound pretty good just doesn't hold . has a s&s super e carb looks pretty clean. I took it apart and cleaned every jet and hole , gaskets and rings don't look bad. friend of mine suggested to tear the motor and stroke it to at least 80 inches , which I might just do over the winter , motor sounds so good and smooth , just think she should run a better.
