Product Description

This high quality OEM sourced item is specially designed for use with Walbo carburetors. Its purpose is to allow user to pump gasoline into the gas chamber. By pressing on the primer bulb it will force fuel into the line from the tank into the carburetor. Once the carburetor is full of fuel, the excess fuel will be sent back into the tank. Over time the primer bulb may lose its elasticity or crack eventually requiring replacement. It is made from durable rubber with a plastic adapter and it is sold individually.

how do I replace primer bulb?
For model number 123c
Fix.com logo
Hi Fred, thank you for your inquiry. Remove the air filter cover and filter, then use a Phillips head screwdriver to unthread the mounting nuts or screws securing the air filter housing. Lift the choke lever up and remove the air filter housing to access the primer bulb. Use a Phillips head screwdriver to unthread the screws holding the primer bulb mounting plate. Pull the plate off to expose the primer bulb. Pinch the old primer bulb with your fingers or pliers to break its seal and pull it out of its housing. Insert the new primer bulb into the mounting plate. Glad to be of help!
