FAQ

This primer bulb replaces OEM part numbers 530071835, 530047213, 188-513, 188-513-1, 188-518, and 188-518-1.
The most common signs are the bulb becoming stiff, cracking, turning yellow, or failing to draw fuel into the carburetor when pressed. If the bulb does not return to its original shape after being pushed, or if you notice fuel leaking around the base of the bulb, it should be replaced.
Primer bulbs are made of specialized rubber that eventually degrades due to constant exposure to gasoline. The use of fuel containing higher concentrations of ethanol can accelerate this process, causing the material to harden, crack, or lose its flexibility.
Installation is straightforward and typically takes about 10 to 15 minutes. You will generally need a small screwdriver to remove the retaining screws or the mounting plate. Ensure the area around the carburetor is clean before removing the old bulb to prevent debris from entering the fuel system.
This bulb is compatible with a wide range of Poulan, Craftsman, and other AYP-manufactured gas chainsaws, including the Wild Thing, 2375, 2150, 1950, 1950LE, 1975, 1975LE, and 1900 series. It is also designed to fit specific Walbro carburetors, such as the WT-119C and WT-265.
Yes, it is a good time to inspect the fuel lines for any signs of cracking or brittleness, as these often degrade at the same rate as the primer bulb. If the fuel lines are stiff or discolored, replacing them at the same time can prevent future fuel delivery issues.
