lol your idea of spot on is abit different to mine then.....I thought you were referring to strobe timing ie trying to set up the timing to with in 1 degree of what ever spec your looking at (of which you cant do on a engine with a fixed CPS as the tdc is already preset). But yes, you do have to get the timing lined up with regards the timing marks on the aux pulley and the groove on the dizzy body......1 tooth out is alot lol.
