My RPM gauge does not show anything at startup on right engine. Then at
runup it comes to life at high RPM. Then after that it works fine. It
wobbles a bit sometimes in the air. My take is that my tach generator
is the problem. Any other ideas. Also do you know where to get a
replacement unit or overhaul?


Because of the location of the tach generator it is susceptible to getting
oil into the cannon plug connector. The first thing I would try is to undo
this connector, thoroughly clean and re-connect. If that doesn't help you
can try swapping sides as Mike suggests to determine if it is the generator
or the tach itself.
