Defective Clutch

How to identify a defective clutch?
Problem: The shaft continues to turn even at start up and low speed.

Hi Robert,

A clutch that will not disengage is caused by either the engine idling too fast or by damage to the clutch itself. Unless the idle adjustment on the carb has been changed or you have noticed that the engine seems to idle faster than it used to, the problem is most likely with the clutch itself. Your trimmer uses two clutch plates. Part of each clutch plate is milled so the thin outer strip will flex outward and contact the clutch drum when the proper engine RPM is reached. The clutch plates have likely failed and are constantly contacting the drum.

Here is a link to an article that will provide all of the information you need to replace the clutch drum and clutch plates...

The Clutch Drum is part #308177001 and the Clutch Plates are part #00242. Both parts are available from http://www.ereplacementparts.com.

I hope this helps with your repair!
