Starting engine: Propeller area – clear. Battery master switch – ON. Booster pump – ON. Prime cylinders; four or five strokes of the primer for a cold engine; zero to three strokes for a warm engine. Pull slowly to full charge; push rapidly to atomize the fuel. Booster pump – OFF. After priming make sure primer valve has been shut-off completely, or booster pump will inject raw fuel into cylinders. Ignition switch – BOTH. Energize starter with starter switch held to STARTER position until starter whine ceases to rise in pitch. Release switch. Simultaneously; hold clutch engagement switch to CLUTCH position, Ignition Booster switch to BOOST COIL until engine is firing evenly. As soon as engine fires, throttle back to about 500 to 800 rpm. Do not use throttle to catch a ‘dying’ engine. If oil pressure does not register on gage within 30 seconds stop engine and investigate. Engine warm-up: Start warm-up at 1000 rpm. After oil temperature has reached 40 degrees Celsius (100 dgr. F) adjust to smoothest engine speed between 1200 to 1400 rpm. Mixture control FULL RICH. Hydromatic propeller – Leave at FULL INCREASE RPM. Note never rush engine warm-up.
