Silly Timing question
The first question I would ask, and don't hate me for it, is are you hooked to number 1. Your problem could also be that the outer ring of the balancer has slipped on the inner hub. This can be checked by positioning no. 1 at TDC at the beginning of its power stroke and see if the timing marks align to 0 degrees. Your timing light may also have brain damage and I'd borrow someone elses light and see if they match, personally my experience is that if the light is flashings it's good but I do believe in useing the more expensive lights. :evil2:
