It sounds like you have the 4G for Honda/HS 142 5/8" straight shaft engines.
The clutch bell rides on the engine output shaft with an oilite bushing in between.
That is most likely worn out or at least in dire need of oil.
Pull the cover off, and with a 'long tube' old style oil can you can get some oil to that bushing, but it is best to just take the belt and the retaining bold in the engine shaft out and pull the clutch bell off,
then soak the brass colored 'oilite' or even the whole clutch bell in some regular 30w oil so the clutch bell will spin free on the bushing.
If it's worn out, replace it.
Sorry, I have no source for that, I don't mess with anything with bushings these days.
