Additional information

This engine throttle shaft and lever assembly, part number 632538, connects the throttle control to the carburetors throttle plate so engine speed can be adjusted during operation. Smooth, consistent movement of the shaft and lever helps maintain stable idle and responsive throttle control.

If the engine surges, will not idle correctly, or does not respond to throttle input, the throttle shaft and lever assembly may be worn, bent, or sticking. Excessive play or binding at the throttle plate can also affect engine speed control.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Remove the carburetor carefully, install the new throttle shaft and lever in the correct orientation, and confirm the throttle plate opens and closes smoothly before reassembly.
