951-10639A Carburetor Primer Bulb for Garden Equipment

When small gasoline garden equipment sits for long time and starts cold, it often suffers hard start caused by air in fuel line and insufficient fuel supply. The carburetor primer bulb is the key part to solve this problem quickly. This 951-10639A primer bulb is designed for matching small gas engines and is a common maintenance replacement. The bulb is integrally vulcanized from oil-resistant rubber, with good elasticity and oil resistance. It will not easily swell or age after long-term contact with gasoline, and will not turn hard and brittle in low temperature, resisting cracking and air leakage after repeated pressing. When pressed, it quickly pumps fuel into carburetor and bleeds air from fuel line, greatly shortening cold start time and reducing wear on starter. Its structure is fully consistent with original 951-10639A. Snap-in installation allows hand replacement without extra tools. It is widely compatible with snow blowers, lawn mowers, wood chippers from brands like MTD, Troy-Bilt and Cub Cadet. After replacing old damaged bulb, normal fuel priming and starting function is restored.
