The primer bulb on a weedeater lawn mower is the mechanism that powers the weedeater engine by supplying it with fuel. It draws fuel from the fuel tank and deposits it into the carburetor so that your weedeater can function. If the primer bulb on your weedeater becomes damaged, it must be replace before you can properly power your weedeater again. Replacing the primer bulb on a weedeater lawn mower is a relatively easy process that only requires a few rudimentary tools.

Cloth

Air compressor (optional)

Flathead screwdriver

Step 1

Remove the cover of your weedeater by unscrewing the screws to the cover of the weedeater.

Step 2

Remove the screws that connect the primer bulb mounting assembly to the weedeater lawn mower.

Step 4

Slip the head of a flathead screwdriver between the base of the mounting plate and the weedeater, and press gently upward on the mounting plate to cause it to lift forth from the weedeater so that you can remove it.

Step 6

Place the mounting assembly back into place on the weedeater and screw it back into place with the screws previously removed.
