Suitable for adjusting screws and accessories of the Husqvarna chainsaws 435, 440, 450 and 445.--DTEKGAZ

Original factory specifications, specifically developed for Husqvarna 435, 440, 450, and 445 series chainsaws. Carburetor Adjustment Screw Kit: This product contains a high-precision brass or steel adjustment screw and a matching spring. It is used to replace the original carburetor screw if it is defective (broken, corroded, worn, or lost). By restoring the precise air-fuel mixture at idle (T/LA), low (L), and high (H) RPMs, it effectively corrects performance problems such as starting difficulties, rough idling, poor acceleration, and a lean or rich mixture at high RPMs. This kit is an essential component for carburetor maintenance, adjustment, and repair.
