STARTING ENGINE
In cooler weather, the engine compartment temperature drops off
rapidly following engine shutdown and the injector nozzle lines remain
nearly full of fuel.
In warmer weather, engine compartment temperatures may increase
rapidly following engine shutdown, and fuel in the lines will vaporize
and escape into the intake manifold. Hot weather starting procedures
depend considerably on how soon the next engine start is attempted.
Within the first 20 to 30 minutes after shutdown, the fuel manifold is
adequately primed and the empty injector nozzle lines will fill before the
engine dies. However, after approximately 30 minutes, the vaporized
fuel in the manifold will have nearly dissipated and some slight priming
could be required to refill the nozzle lines and keep the engine running
after the initial start. Starting a hot engine is facilitated by advancing the
mixture control promptly to 1/3 open when the engine starts, and then
smoothly to full rich as power develops.
If the engine does not continue to run, set the FUEL PUMP switch to
the ON position temporarily and adjust the throttle and/or mixture as
necessary to keep the engine running. In the event of over priming or
flooding, set the FUEL PUMP switch to OFF, open the throttle from 1/2
to full open, and continue cranking with the mixture in the idle CUTOFF
position (pull full out). When the engine fires, smoothly advance the
mixture control to full rich and retard the throttle to desired idle speed.
If the engine is under primed (most likely in cold weather with a cold
engine), it will not start at all, and additional priming will be necessary.
After starting, if the oil pressure gage does not begin to show pressure
within 30 seconds in warmer temperatures and approximately one
minute in very cold weather, stop the engine and find the cause before
continued operation. Lack of oil pressure can cause serious engine
damage.
Additional details concerning cold weather starting and
operation may be found under COLD WEATHER
OPERATION paragraphs in this section.
