Section Ill. PRINCIPLE OF OPERATION
1-14. Principles of Operation.
a. General. The 6 HP Military Standard engine is a four cycle four cylinder, horizontally apposed, air cooled,
gasoline powered internal combustion engine. The engine develops its full rated capacity at a governed 3600
r.p.m.
b. Simplified Principles of Operation. A starter rope pulley, provides a means to connect the starter rope for
pull starting the engine. An inline fuel filter cleans the fuel supplied to the engine. The filter comes equipped with
a fuel cutoff valve, that when closed, stops fuel flow to the engine. The engine comes equipped with dry element
air cleaner. On models 4A032-2, -3, and -4 the air cleaner comes equipped with a service indicator. The service
indicator signals when the element requires cleaning. The inlet temperature control varies the amount of
unheated air entering the air cleaner. On model 4A032-1 (serial nos. G000001 through G000500) a stop button is
used to terminate engine operation. On models 4A032-1 (serial nos. G001001 through G004004), -2, -3, and -4a
two position ignition switch is used. When the switch is in the RUN position the engine can be started. Setting the
switch to OFF terminates engine operation
