Larry, are you just pulling our legs or are you serious. Then again I might have misread your post.
Are you saying that a prop repitch will effect the accuracy or calibration of the tach because if you are I must correct you. The tach purely shows crankshaft RPM and has nothing to do with peripheral items including the prop. If the tach has a 10% under-read a prop repitch will certainly allow the crank to spin at a different RPM but the 10 % under-read of the tach will still be there. In other words tach error can only (and I emphasize ONLY) be corrected by shop calibration of the tach. At 02:03 19/01/00 , you wrote: >Wrong! If you repitch, but neglect to inform the tach that you've made a change, >the tach will now read the correct figure.
