Accelerator Return & Exhaust Springs 52mm – Steel Helical Springs – Pack of 20

52mm steel helical springs for go-kart accelerator return and exhaust systems — pack of 20. These springs serve two purposes on a rental kart: as throttle return springs they pull the carburettor throttle butterfly closed when the pedal is released (a safety-critical function), and as exhaust springs they retain the exhaust pipe connection. A weak or broken throttle return spring is a serious safety issue — the throttle will stick open.

Length: 52mm. Steel helical construction. Applications: throttle return and exhaust pipe retention. Pack of 20.
