Glowplug life
Particularly in the case of very high performance
engines, glowplugs must be regarded as expendable
items. However, plug life can be extended and engine
performance maintained by careful use, i.e.:
Install a plug suitable for the engine.
¡
Use fuel containing a moderate percentage of
¡
nitromethane unless more is essential for racing events.
Do not run the engine too lean and do not leave the
¡
battery connected while adjusting needle.
When to replace the glowplug
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 surface has roughened and turned white.
¡
Filament coil has become distorted.
¡
Engine tends to cut out when idling.
¡
Starting qualities deteriorate.
¡
Foreign matter has adhered to filament or plug
¡
body has corroded.
TOOLS, ACCESSORIES, etc.
The following items are necessary for operating the
engine.
FUEL
When the brand of fuel is changed, or the nitro content
increased, it is advisable to repeat the running-in
procedure referred to in the RUNNING-IN paragraphs.
For consistent performance and long engine life, it is
essential to use a good quality fuel containing NOT
LESS THAN 18% lubricant. Please note that with high-
nitro fuels, although power may be increased for
competition purposes, glowplug elements do not last as
long and engine life will be shortened.
REMINDER!
Model engine fuel is poisonous. Do not allow
it to come into contact with the eyes or mouth.
Always store it in a clearly marked container
and out of the reach of children.
Model engine fuel is also highly flammable.
Keep it away from open flame, excessive
heat, sources of sparks, or anything else
which might ignite it. Do not smoke or allow
anyone else to smoke, near to it.
