6. NORMAL WORKING CONDITIONS
It is recommended to use as much as gas your aircraft needs, it depends on your requirements and
as occasion may require. Reach height as soon as possible, above all if you are flying with a delta
motor.
Do not exceed maximum 6200 RPM. Do not run the engine in the climb out at Full Open Throttle
for more than 3 minutes.
Idling rpm should be 2000 rpm. Less than this may cause unnecessary vibrations. Higher idling
rpm will cause a reduction in the fuel / air mixture enrichment in the starting circuit of the
carburetor and may make cold engine start-ups difficult.
Before shut down, the engine should be run until any heat build-up from previous high power
settings (e.g. taxi back to hangar) has dissipated. Run the engine at 3000 rpm for 2 minutes and
then at 2000 rpm or smooth idle speed for a short while.
Do not idle for prolonged periods (e.g. holding point checks) as the normal rich conditions at this
carburetor setting may cause high carbon deposits on the spark plugs and piston rings causing
fouling. At low revolutions, the vibrations are high and the loads on the propeller, gearbox, and
drive train and should be avoided for longevity of the engine.
