Step 5. Attach the glow driver. Step 6. Turn the engine over using an electric starter. The engine should fire within seconds of applying the starter. Step 7. Allow the engine to idle for 30 seconds. Adjust the throttle trim if necessary to achieve a constant slow idle. Step 8. With the glow driver still attached and a helper securely holding the airplane, advance the throttle smoothly to full throttle. The engine will transition to full rpm. Step 9.
How to tell if your glow plug is bad The glow plugs on the market today are designed to provide good service to the user and may last a long time or a short time, all dependent upon the way you choose to operate your engine. Physical indications that you might need to change the glow plug are: 1. Twisted or mangled glow plug element (usually caused by too high a compression ratio). 2. Small “bumps” are attached to the glow plug element. This will generally be most noticeable during the break-in process.
