When to replace the glow plug?

Apart from when actually burned out, a plug may need to be replaced because it no longer delivers its best performance, such as when:

• Filament coil has became distorted.
• Filament surface has roughened while.
• Foreign matter had adhered to filament or plug body has corroded.
• Engine tends to cut out when idling.
• Starting qualities deteriorate.

Glow plug Life:

Particularly in the case of very high performance engines, glow plugs have to be regarded as consumable items. However, plug life can be lengthened and performance maintained as follows:

• Fit a plug suitable for the engine.
• Use fuel containing a moderate percentage of nitro unless essential for contest use.
• Do not run the engine lean, or leave the plug connected while adjusting the needle-valve.
• Use a fuel containing as low nitro as possible.
