FS55R Stihl weed trimmer

cuby · Aug 27, 2019

This starts good and good power, vibrates bad when going from idle to full throttle and at high rpm. Installed new carb and new complete string head. Anyone ever have this problem with the Stihl??

Either the clutch is worn or broken or else the shaft bearings are worn or dry of grease.

took everything apart, clutch looks good, but some play in outside hub bushing that spins on shaft. Not much grease there.

Smoothed up all surfaces and greased bushing in clutch hub, put together , works great. Still some vibration , but not like before.

Thanks for all the help.
