sounds odd, and cant even really think off the top of my head what this could be without going major like the CAM maybe not dialled in correctly, and also the base timng may not be 10 degrees with that cam.
Charge light is usually meaning the alternator is not charging. Meter that out and have a look at that, could just be a fuse or somthing there too.
check tdc of no 1 check dissy if 180 out
