Operating Notes – Quick Reference Guide
13.1 New Engine Notes
This engine has been ground run to a specific run in program and is ready for
flight.
The engine has been
INHIBITED.
However if you intend to store it for any length
of time please refer to Section 5.7.3 of
INSTRUCTION AND MAINTENANCE
MANUAL.
Removing spark plugs and turning over will help periodically.
Before initial start add oil to engine (2.3 litres with cooler), remove one plug per
head and turn the engine over on the starter to remove excess inhibitor. Once
oil pressure is obtained replace plugs and continue start-up sequence.
Remove ALL plastic bungs on engine before starting. EXHAUST (4) CARBY (2)

your RPM when flying with a new engine.
Do not “Baby” a new engine. The purpose of breaking in an engine correctly is to
ensure a long reliable life. All moving parts need freeing up especially piston
rings to cylinder walls. This is best accomplished when the greatest B.M.E.P.
(Break Mean Effective Pressure) occurs. That is at 75% power and above. Early
running of an engine should include periods at high RPM and power settings.
Failure to operate at realistic power settings could be detrimental to engine
condition & long-term performance.
Always take off using full power
– especially when the engine is new.
Avoid heat build up
– monitor CHT and oil temps. Note that Initial temps will be
elevated due to the friction of a new engine. Careful monitoring by the pilot is
needed during this initial period to ensure long life of the engine and its
components.
CIRCUIT WORK is a good sequence for initial run in work.
i)
Abbreviate circuits initially
ii)
Step climbs and climb at shallow angles & higher airspeeds
iii)
Do not carry out glide approaches
iv)
Gradually reduce power
v)
Avoid sudden heating up and sudden cooling down
When you change oil from the “run in” type to the “normal” oil at or around 25
hrs, replace oil filter.
