After fuel has been drawn to the carburettor, flip the

propeller two more revolutions, with intake choked, to

draw fuel into engine.

Above procedure is called priming.

NOTE (IMPORTANT)

The quantity of fuel drawn into the engine by

priming is an important factor in starting the

engine successfully.

When the engine is being started for the first time,

turn the propeller two revolutions after fuel reaches

the fuel inlet, as described above. However, when re-

starting the engine immediately after a run, one

revolution, or even no priming at all may be required.

The engine's requirements will be quickly learned

with experience.

Priming quantity

Turn the propeller 3 to 4

turns counter-clockwise

smartly by finger in the

direction of arrow. Turn

approx. 10 turns instead

when the engine is cold.

Do not energize the glowplug at this stage.
