    Did you pull the carbs and give them a good cleaning? Should also check pop off and mixture settings. Also check the cable running from the throttle bracket to the oil pump. If it is broken i believe the default is oil pump wide open. ( lots of oil!!) Could also remove oil pump and go premix.

    Did you remove all the old gray Tempo fuel lines?

    Carburetors removed, internally cleaned and rebuilt?

    Missing at high RPM is probably the old ignition system. Even if you install the upgrade ignition you still need to make sure the carbs and fuel lines are up to par.

    Oil pump cable should be working and pulling the oil pump arm UP when squeezing the throttle. Incorrect or broken oil pump cable will not affect WOT oil ratio, so it is not a factor in your high RPM problem.

    My signature link has a list of Parts Sources.
