Here is a handy item; a throttle pot torsion spring for many Pride Mobility scooters. Very often a loose or "sprung" pot spring will seriously effect your scooter's behavior. If your scooter creeps forward or backward with no push of the lever, then a worn-out spring is very often the culprit.
Please note that this torsion spring will fit a very wide range of throttle potentiometers of many brands and models. Please look carefully at the photograph, and if the required gap between wire ends is 0.30" (7.6mm) then this is probably the spring you need.
