Flywheel polarity??

Recommended Posts

4xbill
I was having a no spark issue on a 10hp B&S http://www.simpletractors.com/club2/topic.asp?TOPIC_ID=102663 I replaced the points with a Megafire ignition. Nothing. Replaced coil. Nothing. I turned the coil around and i got spark. But then the spark plug wire would not reach if routed correctly. So i put the coil back and i switched the wires on the Megafire. Got Spark. So with the Megafire wired for a Positive Ground ignition or with the coil installed backwards, i get spark. However, i think now it is firing at the wrong point in the rotation???? Do you think the flywhell may be polarized incorrectly? The flywheel may be a replacement, not original. Arghh, this is driving me crazy!

I think Mega-Fire instructions say hook trigger unit per original sketch, but if no spark reverse blue and white(I think)wire and that should work. Flywheel need not be re-polarized.
