na cam timming

Postby gordon5904 » Sun Nov 28, 2010 3:14 pm

is there anyone who can give me a straight answer ,,cam timing marks on my na are very vague ..I can get marks to line up in two positions 1 tooth apart...how many teeth on the belt should there be between the top marks on pulleys ,it looks like 19 works but things dont line up perfectly so 20 works too .
