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.
•
Foreign matter has adhered to filament or plug
body has corroded.
•
Engine tends to cut out when idling.
•
Starting qualities deteriorate.

TOOLS, ACCESSORIES, etc.

The following items are necessary for operating the
engine.
FUEL
Use only top quality methanol-based model engine
fuel.For consistent performance and long engine life,
it is advisable to use fuel containing AT LEAST 18%
lubricant. This engine is designed to run on both low and
high nitromethane content fuels,i.e. from mild mixtures
containing a few percent of nitromethane, up to high-
speed racing fuels containing 40%,nitromethane.
Generally, power output is increased-up to a certain
point-as the nitromethane content of the fuel is increased.
As a starting point, we recommend a fuel containing
10-20% nitromethane, changing to a fuel containing
more nitro only if necessary. When the nitro content of
the fuel is increased or the brand of fuel is changed, it
is advisable to initially run the engine with a richer
needle-valve setting, so that the optimum setting for
the new fuel may be rechecked as described in the
RUNNING-IN paragraphs. When engines are run at
very high speeds and on high-nitro fuels, glowplug
elements do not last so long.
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.
ELECTRIC STARTER AND STARTER BATTERY
Use a 12-volt electric starter
with suitable battery for start-
ing the engine.(15CV-R/R(P))
