Although the entire governor system is
described, only the throttle actuating mechanism
on the carburetor is included in the overhaul

readily, also the governor rotor can be serviced

(2) EXTERNAL VACUUM TYPE - The
external vacuum type governor operates on the
same principle as the internal vacuum type,
however, the source of vacuum is from an external
source other than the carburetor, usually from the
vacuum booster pump. A tee fitting and restriction
is used and are calibrated for the engine and gov
ernor. The same vacuum passages are in the
carburetor castings but blank jets are usedonthe |
