What causes primer bulb not to prime?

If your primer bulb isn’t priming, there are a few potential causes. First, check to make sure that there’s fuel in the tank. If the tank is empty, the primer bulb won’t be able to draw any fuel up into the carburetor.

Next, check the fuel line. If the fuel line is kinked or clogged, fuel won’t be able to flow freely from the tank to the carburetor. The primer bulb won’t be able to draw up fuel if the line is blocked.

Finally, check the carburetor itself. If the carburetor is dirty or the jets are clogged, fuel won’t be able to flow through it properly. This will prevent the primer bulb from drawing fuel up into the carburetor.

If you’re still having trouble, take your lawn mower to a qualified technician to have it serviced.
