Parts for Honda GCV160-LAOS3B: Control Parts

The governor spring is an important part in a lawnmower engine that holds the engine’s throttle open, while the governor holds it closed. The push and pull between these parts keeps the throttle balanced at the engine RPMs that the user wants, relative to the landscape that's being mowed. When a governor spring becomes damaged or disconnected, the engine will no longer run at a consistent speed. The governor spring can be replaced without any additional parts, but the repair will require a screwdriver to remove the air filter and gain access to the springs. There are usually two governor springs within the throttle—a primary and secondary spring—so check both to find which is damaged. Once the damaged spring has been identified, unclip it from the throttle and the housing and replace it with a new spring. This is a genuine OEM replacement part shipped directly from Honda, the original manufacturer, but it also works with Toro, MTD, and Cub Cadet mowers.

The throttle return spring is attached to the throttle body or carburetor and the throttle cable and helps to slow down the engine by closing the valve that allows fuel to flow into the engine. The valve comes off the carburetor, where the air and fuel mix before being sent into the engine. It is made of durable metal that is designed to withstand the high heat of engines. When the spring is starting to fail, the engine may not slow down or reduce power as it should. This spring can become worn over time or damaged by an impact or another incident, resulting in the need for replacement. If the throttle is sticking, this OEM replacement spring can resolve the issue in a matter of minutes. This Honda throttle return spring is a genuine OEM part that is compatible with many Honda engines, including those in the GCV and GSV series. It can also be used with Toro, Cub Cadet, Lawn-Boy, MTD, Briggs & Stratton, and other brands of lawn equipment with compatible engines. This product is sold individually.
