Engine Start

If the engine is warm, no priming is required. For the first start of the
day and in cold conditions, prime will be necessary.
Weak intermittent firing followed by puffs of black smoke from the
exhaust stack indicates over-priming or flooding. Excess fuel can be
cleared from the combustion chambers by the following procedure:
• Turn fuel pump off.
• Allow fuel to drain from intake tubes.
• Set the mixture control full lean and the power lever full open.
• Crank the engine through several revolutions with the starter.
• When engine starts, release ignition switch, retard power lever, and
slowly advance the mixture control to FULL RICH position.
If the engine is under-primed, especially with a cold soaked engine, it
will not fire, and additional priming will be necessary. As soon as the
cylinders begin to fire, open the power lever slightly to keep it running.
Refer to Cold Weather Operation

If airplane will be started using external power, keep all personnel and
power unit cables well clear of the propeller rotation plane.
Alternators should be left OFF during engine starting to avoid
After starting, if the oil gauge does not begin to show pressure
within 30 seconds in warm weather and about 60 seconds in very
cold weather, shut down engine and investigate cause. Lack of oil
pressure indicates loss of lubrication, which can cause severe
