Starting Procedure

  1. From a completely closed position, open the needle valve 2 - 3 turns.
    • MAKE SURE THAT GLOW PLUG BATTERY IS NOT CONNECTED. THE GLOW PLUGS MUST NOT BE HEATED WHILE THE ENGINE IS BEING PRIMED.
  2. Prime the engine by opening the throttle valve fully, and closing the choke valve while turning the propeller counter clockwise through 2 full revolutions.
    • If strong compression is felt when trying to rotate the propeller counter clockwise, too much fuel has been drawn into the engine. If this occurs, do not use force! Remove all glow plugs from the engine. Then, ensure that the choke valve is open and turn the propeller clockwise to force fuel out of the engine through the exhaust pipes.
    • Warning!!!! Never close the choke valve when applying the starter to the engine. Doing so will cause too great an amount of fuel to be drawn into the cylinders and will result in hydraulic lock and the risk of severe damage. See Fig. 20
    Note:After the engine has been primed, excess fuel may drip from the carburettor when the choke valve is reopened. Therefore, if your engine is enclosed in a cowl, be sure to fuel proof any surface that may be accessible to these fuel drippings to prevent fuel from penetrating the airframe structure.
  3. Release the choke control and immediately turn the propeller counter clockwise several times so that fuel is drawn well into the cylinders.
  4. From the fully closed position, set the throttle valve approximately half open. See Fig. 22.
  5. Using an Electric Starter with your FS 400:
    • Be sure that the direction of the rotation of the starter is correct.
    • Connect the glow plug battery.
    • Apply the electric starter.
  6. Hand starting your FS 400:
    • Note: Be sure to us a heavily padded glove or chicken stick when hand starting the engine.
    • Ensure that he propeller is fixed in such a way that it is positioned horizontally as compression is felt.
    • Connect the glow plug battery.
    • From the centre of the right blade, firmly swing the propeller counter clockwise.
  7. Once the engine starts, open the throttle valve completely and allow it to run (approximately 10 seconds), with the original needle valve setting.
  8. Make sure that all 5 cylinders are firing.
    • The engine is running properly if white smoke is emitting from all exhaust
    pipes equally. You will find a slight fuel spray from the exhaust pipe of any cylinder that is not firing.
    • If you are not using the onboard glow system and a cylinder stops firing,
    reduce the throttle setting to approximately half open from the fully closed position and re-connect the glow plug battery. You will notice the propeller revolutions will increase once all cylinders are firing consistently.
  9. The firing order of the KAVAN FS 400AR 5 Cylinder engine is 1, 3, 5, 2, 4 as seen from behind the engine. See Figure 2
