Spare parts for the carburetor adjustment screw of the ZOMAX 4000 chainsaw: Set of three pins for idle speed (H), maximum speed (L) and limit switch (T).--DTEKGAZ

This precision carburetor adjustment screw set was specifically designed for ZOMAX 4000 series chainsaws. It includes a high-quality brass or steel adjustment screw and spring, allowing for the replacement of worn, corroded, damaged, or lost original carburetor adjustment shafts. By restoring the precise air-fuel mixture (L and H shafts) and idle speed (T/LA shafts), performance problems such as starting difficulties, rough idling, poor acceleration, and excessively high or lean fuel consumption at high RPMs are effectively resolved. It is an essential component for carburetor maintenance and adjustment.
