The ducts supplied with the engine need to be fitted. See Installation manual.
Occasionally, periodic research and development dictates that changes must occur to
cooling ducts. The ducts supplied with new engines will the latest types and may differ
to those supplied with older engines.

Filters
– Regular inspections are a must for fuel and air filters. Conditions will dictate
when changed. The air box has a rubber flap to give partial inspection of air filter.
Spark Plugs - NGK D9EA are recommended. Refer to main body of this manual for
plug gap. Remember that plugs are installed at around 8 ft lb or given 1/2 turn after
contact with head. 18mm Plug spanner used.
13.2.5
Starting
A warm idle of around 900 RPM will automatically create the right starting environment.
As the engine is run-in on a dynamometer the Idle set screw may have to be adjusted
to give 900 RPM idle when warm.
Normal start requires the application of choke with the throttle closed or just barely
“cracked” (approx 2% throttle). With the throttle on the idle stop the butterfly in the
throat body will be slightly cracked. The engine will be difficult to start if throttle is
cracked open too far.
As the engine is cranked the choke should be pushed off. The engine should fire as
the choke comes off. The choke is only used for a cold start. Prolonged cranking with
choke on will “flood” the intake system, making starting difficult. Should this occur,
leave the aircraft to sit for approx 10 minutes, or alternatively, clear the system on full
throttle momentarily (mags off).
If the Cranking speed is too slow (poor battery or starter fault) the ignitions will not fire,
preventing starting. If jump starting is necessary, it point towards poor battery condition
or faulty alternator charging. Further testing would then be required in these areas to
identify the problem.
13.2.6
Trouble Shooting
While it is unusual for a problem to occur, a methods for finding the source of
“common”
problems are listed in the Trouble Shooting Section 10 of the this manual.
