This is a genuine OEM replacement part designed for use with a variety of power tools/equipment. It is made out of rubber and it is sold individually. 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.

Bulb primer on 25 year old Tanaka trimmer had small age holes preventing proper fuel priming. Starts like a charm now.
Remove 4 screws to access removal/replacement of bulb. No more stubborn starts.

Carburetor problems
I removed the air filter cover and the air filter, then removed the screws that were holding the carburetor on. Removed the fuel lines from the carburetor, then removed it. I watched your you tube video on rebuilding a carburetor.

I replaced the primer bulb. I then removed the heat insulator and replace the worn manifold gasket, then reinstalled the heat insulator. I then installed the rebuilt carburetor with the screws, replaced the fuel lines. Then put in the new air filter, than attached the filter cover.

Question: Primer Bulb

gloria

how to replace it on a tbc220 bush cutter
I think you are supposed to unscrew or pry off a collar that holds it onto the priming pump assembly.
WJA
Hello gloria,

Primerbulb120 is correct. If you remove the screws that hold the 6690859 Diaphragm Cover. You will be able to replace the 6684689 Primer Bulb.

-WJA
In the diagram I looked at for the TBC-220, the primer bulb is a separate assembly connected to the carburetor by a fuel hose. http://www.ereplacementparts.com/tanaka-tbc220-grass-trimmer-brush-cutter-parts-c-34785_34906_34939.html?page=5
