O.S. Engines 46FX-H Ring - Manual (Page 7)

Because of initial tightness, a standard
electric starter may have difficulty in
rotating the engine when cold, before it has
been adequately run-in. In this case, use a
high-torque type starter. DO NOT, however,
confuse tightness with the symptoms of
hydraulic lock caused by an excess of fuel
within the cylinder - often the result of over-
priming. Attempting to force the engine to
turn over in this condition may cause
internal damage. Instead, remove the
glowplug, invert the engine and eject
surplus fuel from the combustion-chamber.
Note:
The MAX-46FX-H RING is a high-
performance engine that has been
developed expressly for "medium-sized"
radio-controlled helicopters.
