set to low.
3. Close the choke and turn on the ignition switch.
4. Rubber stick is recommended to start the engine.
5. Begin flipping the prop through its compression stroke until
the engine fires.
6. Wait for the propeller to stop spinning, turn off the ignition,
and open the choke(s)
7. Switch the ignition back on and flip the propeller again until
the engine starts
8. Warm up the engine for 15 or 20 seconds before advancing
the throttle.
Carburetor Tuning and Care
The use of a tachometer is highly recommended. And, again,
never adjust the needles while the engine is running!
Tuning
1. Using the tachometer tune the engine for maximum power
with the high needle (H).
2. Using the tachometer again: richen the high needle (H) until
the engine runs 100-200 RPM less than the maximum RPM.
Now you should richen slightly on the high needle (H).
Keep the engine run at idle for 60 seconds. Insure that the idle
RPM to be constant. If the low needle (L) is too rich, it may
happen that idle RPM drops until the engine stops;. Lean the
low needle (L) until a constant idle RPM is achieved.
Check the transition with a quick throttle advance. It should
sound like it is making quick steady power.
3. Needle adjustment advice
Care:
Your carburetor screen will need to be cleaned with clean
gasoline and blow off with compressed air after every flight.
Check the choke and throttle plates for tightness.
Trouble Shooting
Problem1.
The engine is flooded.
Solution:
Remove the spark plug; turn the engine to a position where the
fuel runs out and clean it.
