Need to ID year of this engine so I can get some parts. Model number is J15RCRM, and the serial number is 05992700.
I need a repair manual, an impeller, and a part I can't even describe very well, but here goes...a plastic part that is disk-operated from the timing advance disk. As the throttle is advanced this disk rotates and engages a round rubber roller that further opens the carburetor valve. The roller portion has a plastic U-shaped piece that connects the roller portion to a metal rod that is finally connected to the carb valve. It is this plastic piece that broke….
Mdixon, the part you're describing is the Cam Follower. The roller is replaceable too, as they sometimes wear a groove in the roller itself from the advance plate. The small adjusting screw in the Cam Follower is for adjusting the Link and Sync of the motor.
