I was given a Honda atc 200 awhile back, rode it around for awhile until the engine locked up on me. The camshaft bushing got hot and froze to the cam. I got an entire cylinder head off of e-bay for real cheap and I've rebuilt the engine. The problem I'm having now is I'm not getting fire to the plug. I've traced all the wires and everything is in good condition. Cleaned the magnets and stator contacts and still no go. I'm thinking it's either a timing issue or the cdi box junked out while I had it laid up. I can rebuild a lawnmower engine with my eyes closed, but these trike engines are fairly new to me. Would anyone have any ideas of what could be the problem.
