Hello Tormentin,


The shaft in the speed control plate is sealed with a small o-ring. This o-ring is a replacement part.

The speed control plate will need to be removed and the throttle shaft disassembled to replace the o-ring. You will also need a new gasket under the speed control plate when you reassemble.

The internal arm of the speed control applies tension to a governor spring. Use caution that you do not stretch the governor spring or drop the spring into the engine when removing and replacing the speed control plate.

Alternatively, the speed control plate can be replaced as an entire assembly.

Good luck!
