in. Install the propeller securely to the engine, connect the fuel lines, and fill the fuel tank.
Install a long reach R/C glow plug in your engine. Refer to the following starting procedures.
■Filling the Fuel Tank
Disconnect the pressure line from the pressure
fitting on the muffler and fuel line from the fuel
inlet on the carburetor. Connect the fuel line to
the tubing from fuel pump to fill the fuel tank
until fuel overflows into the pressure line indicat-
ing the tank is filled. Re-connect fuel line to fuel
inlet and pressure line to pressure fitting. Be sure
to not let dirt or dust enter fuel container.
■Pre-Adjust Needle Valve
Turn the needle valve clockwise until you begin to feel resistance. This the fully closed position.
Do not force the needle valve or you may
damage your carburetor! Now turn the needle
valve counter-clockwise about 2 - 2 1/2 turns.
This will be a good place to start. (Turn the
needle valve clockwise to “close” for leaner
mixture, or counter-clockwise to “open” for
richer mixture.)
■Choking/Priming Your Engine
Using your radio control system, move the stick to
open the throttle to 1/2-3/4. Place your finger
over the carburetor opening (without the glow
plug battery connected!) and rotate the propeller
2-3 turns or until fuel flows through the fuel line
into the carburetor.
The quantity of fuel drawn into the engine by priming is an important factor for starting your
engine successfully. It needs more fuel for the first starting and when the engine is cold.
■Heating the Glow Plug
Fit the glo-starter or connect the 1.5 volt ignition
battery onto the glow plug. The glow plug is
designed to keep the engine running after remov-
ing the glo-starter or cutting off the ignition
battery. The platinum alloy coil inside the glow
plug is heated up with the starter battery current,
and remains hot to keep the engine running even
after the electric power is cut off.
■Flipping Propeller to Start
Using your radio control system, move the throttle stick so the carburetor barrel is 1/4 to 1/2
open. Flip the propeller to start the engine by using a “chicken-stick” or an electric starter.
The engine should fire after a few flips. When starting the engine, have a helper hold your
