What does a carburetor spring do?
As indicated above, the job of the throttle return springs is to “return” the throttle to a closed position. When the spring is damaged, the throttle body will remain open until either the pedal is manually drawn back by a driver’s foot or gravity takes over and helps to close the throttle.
Are throttle cables universal?
In today’s modern vehicles, throttle cables are obsolete with the widespread use of drive-by-wire throttle pedal assemblies. Our universal throttle cable offerings fit most any application or engine type and mounting location.

Who makes Tecumseh small engines?
In short, Tecumseh engines and parts are currently manufactured by LCT, CPC and Lauson Engines.
Do I need a throttle return spring?
Not needed since the throttle arm has its own spring. But if you find your throttle too touchy, you can install an extension arm to alter the geometry and slow the action down a little. If you go that route, you probably will want a return spring.
What does a throttle return spring do?
The throttle return spring pushes the throttle closed when the driver lets off the gas. A weak or failed throttle return spring will prevent the throttle from easily returning to its resting position. This can result in engine racing and unintended acceleration.
What causes the throttle to stick?
A sticky throttle could be caused by worn cables, lack of lubrication in the cables or the cable getting bound up somewhere in the mechanism. Or it can be caused by an issue with the carburetor or EFI. If the screws in the throttle housing are too tight it could cause the cable to stick.
