after I split the case to repair a bad counterbalance assembly, new piston, and cylinder the engine idled momentarily and won’t run. I do have oil pressure which was the original problem. When I was installing the stator I noticed there is some adjustment that I assume is for ignition timing. I tried to set it in the same screw marks as before. How do I set ignition timing?
Just as you did - the allowable 'adjustment' will not change the timing far enough to make a noticeable difference in performance. Backfiring out the exhaust is most commonly caused by a spark plug or another ignition issue.
