Tachometers compatible with revinator ignition

I find it odd you're having troubles. I run the rev-n-nator unit with that same white face, push the needle around the face aftermarket basic cheap tach (sunpro I think). Runs fine.

When you say they do not function properly whats going on? Most common problem with tach not reading right or "tic tocing" or anything like that is an electrical interference with your wire to the negative side of the coil. It has to pickup a clean signal to work the tach. As far as I know.
