To stop engine leave accessory switch on and pull out "engine
stop" handle until engine stops. Note it has a ridged side and a smooth
side. The ridged side is so you can " lock" the stop handle in the out/no
fuel position to prevent the from starting until you manually release it.
Do not shut the accessory switch off until the engine is off and not
rotating THEN shut off the accessory switch. WHY? Because the accessory
switch provides electrical power to the alternator to magnetize it so it
can create power.

Answer? You can pump to your hearts joy and it is not a carburetor
and will not pump any fuel unless the engine is turning over either by the
starter or the fuel firing and running the engine.
The hand and foot throttle are connected to the governor which
takes the demands ( throttle movement by hand or foot pedal which the
governor passes on to the high pressure pump that actually delivers the
fuel in metered amounts to the injectors that inject the fuel into the
respective cylinder. As the engine approaches the maximum setting for the
governor it backs off the fuel delivered until the engine no longer
accelerates or climbs in RPM.
