Starting
1. Always wear a heavy leather glove when starting the motor.
2. Check that prop bolts are tight and spinner is secure.
3. Make sure the starting area is free of dirt, sand, gravel, or other loose debris
4. Turn on the radio system and check the throttle operation and position.
5. Have someone (with eye protection) firmly hold the plane from a position behind the wing.
6. Close the choke completely.
7. Open the throttle to approximately 1/4 position.
8. Turn on the ignition.
ALWAYS BE PREPARED FOR THE MOTOR TO START ON ANY
FLIP OF THE PROP
, whether the ignition switch is on or off!
9. Give the prop a quick, firm, flip counter clockwise. Follow through quickly as you flip the
prop so that your hand is out of the propeller's path. Repeat until the motor fires or “pops”.
10. Open the choke.
11. Set throttle to idle position. (carb butterfly plate slightly open)
12. Flip the prop again until the motor runs.
13. Let the motor warm up for 15 or 20 seconds before advancing the throttle.
Needle Adjustments
• The needle farthest from the motor is the “High End” needle. The needle closest to motor is
the “Low End” needle. Turning the needles in/clockwise “leans” the fuel mixture. Turning the
needles out/counter-clockwise “richens” the fuel mixture.
• Settings will vary with altitude, temperature, humidity, fuel, carb variances, etc. A "general"
starting point for the KCS62 is: 1 3/10 open on the Low needle, 1 open on the High needle.
• Adjusting either needle can have a slight effect on the other. Example: Leaning the low
needle can "slightly" lean the high rpm range.
• Adjust the High End needle to peak rpm. A tachometer can help, but remember that the RPM
normally drops a little bit after every start due to residual heat build-up. Don’t lean the mixture
any more than necessary. If the rpm steadily drops at full throttle or fades on long vertical
maneuvers, the motor is too lean and is overheating.
