cam phase checking is only intended to be used with the engine running.
set the engine at tdc according to the balancer, then rotate 1.5 inches further (continue rotating the engine in its normal direction.)
another way is to set the engine at tdc, and make a pencil mark thru the timing tab at 15degrees. then rotate the engine until this mark is at TDC, then make a mark at 10 degrees and rotate until this mark is at tdc.
then rotate the cam sensor clockwise until the cam light is off, then counterclockwise until the cam light just turns on.
