Twist grip throttle stuck at idle
Hi George. Brad may be right with his answer but there might be something you can do.
Does the throttle open/turn as it should or is it stuck in the closed position and will not turn at all?
If it won't move then it could be a seized cable, a stuck mechanism at the carb end or a twisted or kinked cable.
If it does move but the engine doesn't rev it could be a broken or disconnected cable.
On top of the carb there is a mechanism where the cable end fits and this is pulled to rev the engine. Have a look and see if there is a cable attached. There may be 2 on yours, one to open the throttle, the other to close it and snap the throttle closed which is aided by a spring. When you open the throttle does this move? Yes, then the cable is doing its job. No, then the cable is not operating properly and is either broken or has come away at the throttle end and will need looking at. With the engine idling try to move the mechanism manually and see if the revs increase and then drop off when you release it (you might need a screwdriver to reach in to do this). If it revs and drops back down as it should, then the mechanism is operating as it should, If it doesn't alter the engine speed despite moving back and forth then it has detached itself in the carb and that will require investigation. At least if the cause is found it could be an easy fix, or cut the mechanics costs by pointing him in the direction of the fault.
