Noisy centrifugal clutch

[Cotmullion]

I have a Comet centrifugal clutch and today when I the engine turned it on, the clutch had a clunky, loud noise coming from in it. What is this?

Not sure..........But I'd bet it would get a lot of hits on You Tube.

Probably just needs some cleaning & lube. I've been using some Torco MPZ engine assembly lube lately. It's some thick & sticky stuff with molly suspended in it. You will need to either thin it out some with WD-40 so it can flow into the bushing area. Or remove the snap ring & separate the clutch halves to directly access the bushing. Then you can just smear it on with your finger.

Sounds like it could use a drop of oil on the bushing, was it cold?

My mini has been surging. I thought it was because I had the throttle cable a little rigged.
HRM? Spray the clutch with air and oil huh? Cool will try tonight. I might swap out the clutch if that does not work, I have a spare.

A clunky noise will be more than lube. Take it apart and check the springs and shoe's. when lubing, only lube the bushing.

My Allstate used to make that noise back in the late 50's and a drop of oil on the bushing would fix it for a few days.

I cut it off twice and it's still too short!!:smile:

My Cushman started making horrendous noises too yesterday at the festival I was using it at as well. Bushing was/is the culprit. You make fine adjustments to the chains by moving the transmission I think I pulled it a little too tight on the clutch side chain. I'm a little upset that its allready doing that Its only 62 years old, made in America crap:wink:
