<VV> Corvair Tachometers

[James Davis]

The tach do have an adjustment hole in the back case. It is in the 
upper right quadrant as viewed from the back. Originally it was 
covered with a paper stick-on seal.  Be sure an use a plastic pot 
adjustment tool not a metal screwdriver.  Sixty cycle household 60 
cycle standard equates to 1,200 rpm.
