Your motor needs 5 degrees before tdc so you are actually running the motor 5 degrees off the factory setting. The bb is tdc. Find the hash mark or use a dial back light and get to 5 btdc before you readjust the carb. Also, did you check the vacuum advance for operation? If you look at the factory shop manual (See Keith hardy's On line Manuals if you dont have one) you will see that the hash mark is the first radial line clockwise from the bb. You need to get this motor to a factory baseline first and foremost. Then you can tinker with adjustments from the factory specifications.
