RE: How to start plane engine/URGENT
In short:
To run, the engine need: Air, fuel and a glowing plug to set it off.
1. Open carb to full throttle, cover the air intake of the carb with your thumb and spin prob.
This is done to prime the engine, the goal is to get some fuel into the cylinder.
2. Close carb to idle, make sure you have the linkages correct so when idle, there should be a small slit open in the carb.
3. Apply power to glow plug
4. Hold the plane firmly, or teather it to something
5. Spin prop to fire the engine
6. Remove power from glow plug
