Glowplug 11 - O.S. engine MAX-15CV-R Series Owner's Instructions Manual

The starter prevents the engine from being
rotated in the wrong direction.The unit will
be damaged if you attempt to force the fly-
wheel in the opposite direction (i.e. clock-
wise when viewed from the crankshaft end).
NOTE:
Because, in the interests of personal safety,
dismantling of the starter mechanism is
strongly discouraged, the Recoil Starter is
available for replacement only as a pre-
assembled unit.
However, some related parts, such as
Starting Shaft and Rear Adaptor, are
obtainable separately. (See Parts List.)
GLOWPLUG
Since the compatibility of glowplug and fuel may have
a marked effect on performance and reliability, it may
be worthwhile to choose the R/C type plug found
most suitable after tests.Recommended O.S. plugs
are No.8, A5 and A3. Carefully install plug finger-tight,
before final tightening with the correct size plug
wrench.
The role of the glowplug
With a glowplug engine, ignition is initiated by the
application of a 1.5-volt power source. When the
battery is disconnected, the heat retained within the
combustion chamber remains sufficient to keep the
plug filament glowing, thereby continuing to keep the
engine running. Ignition timing is 'automatic' : under
reduced load, allowing higher rpm, the plug becomes
hotter and, appropriately, fires the fuel/air charge
earlier; conversely, at reduced rpm, the plug become
cooler and ignition is retarded.
Glowplug life
Particularly in the case of very high performance
engines, glowplugs must be regarded as expendable
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 the needle.
