Skippii, it was the jetting. I swapped the main jets to 112 and it pulls strong from 7k+.

The other problem that is occuring is at idle. It doesn't want to start unless I give it gas and full...

Perhaps it's the regulator/rectifier? I'll check it out tonight with a multimeter (should have done this sooner...). Does anyone have one they could sell to me and get it shipped asap? Thank you.

Update, I do think it is the CDI. If I let the engine idle at 4-5k for a few seconds and then apply throttle it will rev maybe 2-3k, if i left off and apply throttle again it revs a little lower,...

Skippii, it's always idled that low for 2 years, I don't think it's too low... Even when choke is applied and the idle is raised to 4k any application of the throttle chokes the engine.

Haha, seriously? I have not tossed it back in there for the sake of having a piece of metal just bouncing around in my carbs. I'd rather find out where it came from.
