Carburetor Assembly
The surging behavior is a direct result of a lean combustion event where the governor hunts for a stable RPM due to a restricted idle or main jet. This mechanical restriction, often caused by fuel oxidation or debris, prevents the venturi effect from drawing sufficient fuel into the air stream. Replacing the complete assembly ensures that all internal fuel-air mixing circuits and the integrated fuel selector valve are restored to factory flow specifications.
