So I've been rebuilding this motor for several weeks. Originally it didn't start, because it had no spark. We replaced the switch box (still no spark) then Stator and bingo running like a scolded dog just a little rough . Then had no trim, replaced the trim motor now trim is working fine. Lastly was the carbs running rough. I rebuilt all three of them but don't know how to adjust them so it starts with heavy choke and a lot of throttle.
