Valve Timing Best to use Jerry Howell's timing charts to set inlet/exhaust valve timing. Made flywheel disc size discs for mounting on to f/wheel to set timing. Timing discs takes time to be be understood and accepted. The rotational direction seems wrong CW v/s actual CCW. However with exhaust timing disc stuck on and a trial cam setting confirmed Drawing was correct. For the very first time I get to preset cam timing and sleep in peace.
