Squealing noise around stator and slow return to idles

[Brickyard]

I've recently discovered a squealing noise while trying to diagnose some problems I'm having with my '66 CB77 with a rebuilt head. Apparently its coming from or behind the stator and I feel like I'm causing more damage every time I let her get hot. Please help!

The other problem I'm having is a slow return to idle (lean running conditions, maybe?) Heres what I've done up to this point:

1. Set mixture screws to 1 1/2
2. Fixed air leaks
3. Clear fuel lines to verify fuel flow
4. Timing and advance at 3500 rpm
5. Verified slides are straight, true and operate the same

Please help!

Disregard the second problem. After 1.5 years I realize what carb slides are.

Pull off the rotor and check the starter clutch. Sometimes the cover screws back out....

Thanks G.

Come to think of it, I did undo those screws for no other reason than seeing if something was broken, and didn't do the best job tightening back up. I'll get right on it!

If you look carefully, there are slots in the part next to the screws. Take a punch or small chisel and 'stake' the edges of the screw (when tight) into those slots.

Yes! Common problem! I didn't see the slots, but now I use loctite. I've had this same problem. GG

Pulled rotor, attempted to tighten screws but they went no where, shaved sharp edges, and squeal or "squeak" still exists. Can't really spot where the sound is coming from, but it doesn't sound like the rotor. It sounds the same on both sides of engine. I'll adjust the cam chain and try again
