Sweet i love it i read in the manuel the firing order is 1,3,4,2 clockwise from 1 of course. So im sitting at tdc my dizzy is on number one and the pulley timing mark is facing up sound good. now one final question. i put the motor at tdc with the head off not really sure how to determine which stroke its on. would this matter considering its not building up any compression with the head off or do i get to do this again to make sure im not 180 off.
