Hello All, I'm having trouble adjusting the carb - I adjust the Slow Speed needle valve as directed in the Top Secret Files and the motor runs fine. My problem is at mid to full throttle - the motor really starts to buck/misfire bad - I turn the Slow Speed needle valve out and the bucking almost stops. Am I missing an adjustment?

The coils, points, plug wires, plugs and condensers are new. Points are set at .020

The carb has a new idle needle and jet.

Any suggestions will be greatly appreciated

Did you overhaul the carb when you installed the new needle and jet?
