Don't know the timing numbers. Tried to set the timing with a light but I'm guessing the mark has moved or was never marked right. I set it the digital tac on my timing light to where I got the most RPMs out of the motor, re adjusted the carb and haven't had a chance to go back and play with it anymore. I know thats not the best way to do it but Uncle Sam is shipping me out and I'm just trying to get this safely drivable so my mom can take it out to show nights and keep it moving while I'm gone.
