Description

A primer bulb is a small rubber button-like component. This essential part pulls fuel through the fuel line and helps fill the carburetor with the right amount of fuel. Pressing the primer bulb will start the fuel flow and combustion. The primer bulb makes starting the engine easier, and without it, undue stress will be placed on the carburetor. There should be a slight resistance when pushing it and it should pop back out after depressing it. If the primer bulb is cracked or is not creating proper suction, replacement is necessary. The rubber material will eventually harden and crack over time. Stale fuel can also cause primer bulb deterioration. To replace a primer bulb, it is best to consult the equipment's manual for diagrams that show the bulb's placement. This is an OEM part made from high-quality material and is manufacturer-approved for use as a replacement. It can be used in lawn maintenance equipment such as string trimmers, leaf blowers, chainsaws, and pole pruners from brands like Craftsman, Husqvarna, Weed Eater, Poulan, and Poulan Pro.
