Three brands of carburetors are used on the WM 80 engine: Walbro
(1), Tillotson (2), and Bing (3).
The Walbro and Tillotson carburetors have internal fuel pumps while
the Bing uses gravity feed to supply the fuel from the tank to the
engine. With the Bing carburetor, the fuel tank must be located above
the carburetor for the fuel feed to work properly. The fuel pumps on
Walbro and Tillotson carburetors operate on differences in air pressure
between the atmosphere and the crankcase. No matter the design, the
carburetors can be used at different angles and are very tolerant of
high vibration.
As of the publishing of this manual, only one version of the Walbro
carburetor has been used. It is a fixed jet design. It features an air
purge system.
Three different versions of the Tillotson carburetor have been used:
Dual Needle, Single Needle, and Fixed Jets With Primary Idle Bypass.
See section Tillotson Carburetor Versions.
Two different versions of the Bing carburetor have been used: one with
a metal inlet control lever and a plastic choke, and another with a fixed
plastic inlet control lever and a metal choke.
