Default RE: Pullstart Airplane Engine?

IBrakeForNobody,
Ok, the problem you are having with flip starting it is more than likely a simple matter of priming the motor. Here's a pretty simple way to prime your motor:

- MAKE SURE THE GLOW DRIVER IS NOT CONNECTED
- Open your throttle wide open
- Cover the air intake of the carb with your finger (for a 4-stroke or limited access to the carb cover the exhaust outlet of the muffler)
- Flip the motor counter-clockwise. As you flip through compression you should see fuel being pulled up the fuel tubing. Keep flipping until you see fuel get to the carb. Flip it 1-2 more times to pull some fuel into the carb. Remove your finger from the carb and flip the motor 3-4 more times to pull the fuel into the cylinder.
- At this time close the throttle to idle, with your throttle trim all the way open. Put your glow driver on the glow plug. At this time, when you slowly turn the prop WITH A CHICKEN STICK as you approach the compression stroke you should feel the prop kick back. This is the best thing, it means your motor is properly primed. Use the chicken stick to flip the prop through the compression and the motor should fire.
-if you have too much fuel (motor flooded) the motor will run backwards. Use your throttle to kill the motor. Flip again. should only take a time or two to burn off the excess fuel for it to run correctly.

each motor has is a little bit different, but this should be a good starting point to get it going. Adjust for your motor until you get the feel for flipping it. One reason I like to be able to start with a chicken stick is to take care of things when I'm on the flight line. I put my glow driver and chicken stick in my back pocket. If I have a dead stick or a ground loop that kills my motor, I move my plane on to the grass on the side of the runway and I restart it right there with no need to head back to the pits to restart.

Give it a try and you'll find that you really can live without that starter. I have one and it rarely leaves my flight box.

Hope this helps
