Okay. Haven't put a light on there yet, but I'm almost certain the timing is good. I know that it HAS been advanced, just after it's recent build, and about every other time when starting the engine, there is a little clunk in there (slow skip for a lack of better description), that indicates the timing has been advanced. If I don't put the light on there now, what's the next step? OR, am I hearing that I need to put the light on there anyway? If so, I gotta order one.
