vacuum leaks fixed but needle still bounced 18-21. did run better though. adjusting valves and lifters seemed too week and couldn't adjust enough to stop the clattering. replaced them and found the ball from one of the pushrods smashed and laying there! new lifters, an old spare push rod and adjusted valves. rock steady vacuum just above 20 psi. now to check my jetting WITHOUT vacuum leaks and mess with the advance curve as both are surely off.
