  knowing the rpm is not necessary. Take the idle down to a pleasant smooth purr, without any lope. The idle rpm is not a critical setting.

  A vacuum gauge is a good tool to set idle speed. After obtaining the desired rpm, usually around 500-600, adjust the idle needles for maximum stable reading.

  When flying radio controlled air planes I had a hand held tach. You just held it in front of the prop.This was 30 years ago.
