I have rebuilt this motor so I know it is mechanically sound. This is one of several I have rebuilt down the years.
Idles as it should and picks up well but bogs at around 3k. Tried shooting fuel mist into the intakes while running at bog speed and no change in RPM. That should eliminate fuel as a problem. Throttles go wide open and advance retard seems to be in order. I have been told that the switch boxes have a transition point at about 3K and that although the sparks are real good the boxes may not be performing correctly.
Can anyone help me on this please?
