O.S. Engines 61LX-H - Manual (Page 7)

Because of this 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 ringed-piston MAX-61LX-H, MAX-
61LX-HG(R) and MAX-61LX-HGL are high-
performance, high-quality engines that
have been developed specifically for
radio-controlled 60 class helicopters.
They are ideal for scale and sport flyers,
for newcomers to 60 class helicopters and
for contest flyers' first-line or reserve
models.
These motors are produced by the world's
oldest and largest model engine design
and manufacturing company, a company
that has built more helicopter engines
than any other manufacturer worldwide.
