installed centerline is 106, which is 4 degrees advanced. if you installed it straight up, it would be at 110 i/c, 4 degrees retarded. you would not be happy. it needs to be at 106.

OK, you might have lost me there but the crank and cam sprockets are lined up at 0-0 and using the degree wheel and doing the check procedure I get 106' which is the centerline value given for the cam. I've heard of advance being "built in" by cam makers if that is what you are referring to? BTW the crank sprocket adjustments are in 2' increments only (not a 'hex-a-just' unit) .
