As the original engine was designed to run on Very low octane fuel (68) the timing had to be set accordingly. I set all my engines at about 5 deg, btdc with no problems. also remember, the timing marks on any given engine can vary a couple degrees, due to manufacturing tolerances, so try this first and adjust accordingly.
