It's very well possible that the rotor is getting too far from the desired terminal on the cap when its firing. you need to make sure the vacuum advance is locked out in the full advance position then setup your dizzy in the motor. Then use an old cap with windows cut out to see where the rotor is lining up in reference to the desired terminal.
