Thanks Peter and Bob, And for anyone else pondering this, I just put the
old points distributor back in and the symptoms did not change. They say
the carbs are usually not the problem, but it sure looks like mine are
messed up. To reinterate, I have excellent idle and operation at low RPM.
Cutting out starts @ about 2K under load. I can nurse it up to about 3K
max. Also cuts out worse up hill. Thanks again.
