About Tecumseh Primer Bulbs:

There are four types of primer bulbs
found on Tecumseh engine carburetors.
Two of these styles have an external
center vent hole and the other two are
internally vented and do not have a hole.
Using the wrong primer bulb in your
Tecumseh carburetor can result in poor
engine performance and difficulty in
starting. Visual identification is usually
adequate in determining the proper
primer bulb for your model; however
more detailed information on Tecumseh
primer bulb and carburetor identification
can be found in our Tecumseh repair
manuals section.
