Hello- I am stalled in rebuilding a spare kt250 engine that was seized. I have rebuilt the lower end, and before I spend the money for a bore and new piston, etc., I want to make sure I can get a spark. I have the flywheel installed, and I have a CDI unit, but I do not have a coil. I'm looking for an aftermarket coil but I can't find out whether I need a 12v or a 6v coil. I know the lights are 6v, but the ignition coil on the magneto may not be 6v as well. Does anyone know which voltage coil I need, or maybe which coil specifically I could use? I found a couple of reasonable coils on ebay that say they are compatible, but I'm skeptical. And of course the used kt parts on ebay are usually shot AND super expensive. I think it's a cartel...LOL Any help would be appreciated, Larry
