Fuel System, Gasoline — Carburetor System

Summary

The throttle shaft of the carburetor may crack and eventually break at the threaded hole for the throttle plate connection due to excessive vibration of the throttle shaft. Consequence of defect: If the throttle shaft breaks, the throttle would not return to its idle position. This could result in loss of control and an accident.

Actions

Install a reinforcement plate if there is no crack in the throttle shaft. Install a new carburetor with reinforced throttle shaft if a hairline crack has developed in the shaft.
