Step 2E. Starting the Engine
To start the engine, you need the following items:
• We recommend a high-quality, 2-cycle fuel containing 10–15%
nitromethane, such as Hangar 9 Aeroblend, Cool Power
or Powermaster fuels.
• Fuel pump
• A chicken stick, such as Hangar 9 Start Stick,
or electric engine starter
• Glow driver
Note: If this is the first time you’ve run a model engine, we
suggest that you get someone with experience to help. Your local
hobby dealer may be able to help or put you in touch with an
experienced modeler who would be willing to help you.
Presetting the High-Speed Needle Valve:
1. Fill the tank with the recommended fuel.
2. Connect the fuel line to the carburetor and the vent line to the
muffler pressure nipple.
3. Turn the high-speed needle clockwise until you feel a slight
resistance. This closes the needle valve completely.
4. Now, turn the high-speed needle counterclockwise a total of 2
1
⁄
2
turns. This should be a good place to start and will give a rich
full throttle setting.
Presetting the Low-Speed Needle Valve
1. Close the throttle barrel and screw the low-speed needle in until
resistance is felt. This closes the low-speed needle. Now open
(counterclockwise) the low-speed needle 2
1 ⁄
2
turns. This will give
a slightly rich initial idle setting.
2. Open the throttle barrel to the full throttle position.
3. Place your finger on the carburetor opening (make sure
the glow plug battery is not connected) and rotate the
propeller counterclockwise several times or until you see fuel
flowing up to the carburetor through the fuel tubing.
4. Reduce the throttle to idle (1/16” opening in throttle barrel).
