funny, first thing i thought was "ok, slip the sprocket / cam to get where you need". this does bring up the question of whether you want to install the cam "straight up" or pick up a little adv / retard.
Yeah I just wanted it to be correct and since I have more time than most to build this engine I wanted to see who made their parts wrong. All I can say is be careful when using the high dollar double roller. Make sure and check.
