This is a genuine OEM replacement part designed for use with Walbo carburetor. By pressing on the purge bulb, it will force fuel into the fuel line from the fuel tank into the carburetor. Once the carburetor is full of fuel, the excess fuel will be purged back into the tank in the fuel return line. At some time the primer will lose its elasticity or crack and need to be replaced. It is made out of rubber and it is sold individually.

primer bulb
The original primer bulb was cracked and unusable. The bulb was easy to replace and along with new fuel line and a filter it runs again. It was a very easy fix. - Thanks

2. Removed the screws and the plate holding the old bulb.
3. Set the new bulb in place.
4. Replaced the original plate and the screws.
5. Primed the engine and it started perfectly with no leaks.
Used screwdriver to remove primer bulb and mounting plate. Inserted new bulb into plate and reattached with screws. Tested by cranking hedge trimmer. Worked like new.
I removed the old broken primer bulb by unscrewing the two screws holding the capture clamp. Removed the old primer and inserted the new ptimer bulb. Replaced the screws holding the clamp and tightened them. Tried the primer and it worked as it should.
I disassembled the carburetor, cleaned it, reassembled it.
