Problem #1: The plane lands, at the end of a flight, with a much higher idle than it started with (guess that’s better than a lower idle [
] ).
Problem #2: If I move the throttle quickly from idle to open the engine will hesitate or die unless I catch it by reducing the throttle. It does not do this going from wide open to idle quickly.
You are lean on the high end...
Hewre is how I do all my engines as instructed by RCIGN1
Open both 2 turns
Start engine
Lean out high speed needle for max rpm, then back off about 200 rpm
Slowly lean low needle and try transition
Do it until no transition
Open low slightly until transition is good
Re set high, leave slightly rich
If the ‘H’ needle is too lean, it may cause the following three symptoms.
1. Engine stops at full throttle.
2. Engine hesitates when accelerated rapidly.
3. The engine will not come up to full RPM at full throttle.
If the ‘H’ needle is too rich, it may cause insufficient RPM at full throttle. This
causes carbon buildup on the spark plug.
If the ‘L’ needle is too lean, it may cause the following three symptoms:
1. The engine hesitates when accelerated rapidly.
2. The RPM increases at idling.
3. The engine stops when the throttle is moved from high to low.
If the ‘L’ needle is too rich, the idle may be unstable.
The position of the ‘H’ needle will vary according to air temperature and
field elevation.
