Craftsman trimmer

I have a craftsman trimmer and when I engage the throttle it will not move the head it is still linked to the carb and the cable is not broke and the one in the shaft is not either for pics of it please check out my thread I. Small engine & mower repair under the same name

I had my ryobi apart to lube it at its half life (5 yrs old) Seems like you need to check the drive , including the pinion gears . It is possible to pack lube or zerk lube them. I had some looseness where the drive shaft fitted into the pinion gear, did some washer shimming, but can't remember the details. Have you tried loading (holding stationary) the head while turning the engine by hand?

The same thing happened to my craftsman weed wacker. I lubed it up and now it works like new. I think I used Royal Purple but not sure.
