Reminder! Model engine fuel is also
highly flammable. Keep it away from
open flame, excessive heat, sources of
sparks, or anything else, which might
ignite it. Do not smoke, or allow anyone
else to smoke, near to it.
The suggested propeller size is listed on
page 13. The suitability of the prop depends
on the size and weight of the model and
type of flying. Determine the best size and
type after the engine has been run in.
Check the balance of the propeller before
fitting it to the engine.
Unbalanced
propellers cause vibration and loss of
power. Wooden propellers are to be
preferred. Some nylon propellers are not
strong enough to withstand the high power
output of these engines and a thrown blade
can be very dangerous.
Reminder! Never touch, or allow any
object to come into contact with, the
rotating propeller and do not crouch
over the engine when it is running.
Two mixture controls are provided on
these engines.
•
The Needle Valve (at rear of engine)
When set to produce maximum power at full
throttle, this establishes the basic fuel/air
mixture strength. The correct mixture is then
maintained by the carburetor's built-in
automatic mixture control system to cover
the engine's requirements at reduced
throttle settings.
•
The Mixture Control Valve (carburetor)
This meters fuel flow at part-throttle and
idling speeds to ensure reliable operation
as the throttle is opened and closed. The
Mixture Control Valve is factory set for the
