I just reinstalled my exhaust and worked a little on the timing. I just cant seem to get it. Is runs the best when I turn it all the way counter clock wise. Its still doesnt run right when I do that and my timing light says its way off. I got new plugs in this thing also. The other day I cleaned the carb bc it had 26 years if gunk on it. After it ran for about 15 mins i noticed leaks around the carbs base and a few other spots. I just bought a remaned carb so should go ahead and swap em? I wanting to get the timing correct before I swapped the carb. What to do, what to do?
