Hey folks. I just acquired a Lost World machine and the grabber stopped working. The timing belt is in good condition and connected to both gears just fine. The motor seems to spin, and the grabber drops. The grabber does not however come back up when the motor is trying to lift. It starts, then it jerks around and "jumps" for lack of better words. the top of the grabber will not fold back up and thus wont raise up.

Any help or advice on where to start looking for issues is greatly appreciated. Thanks all!
