Note:
As delivered, the carburetor is not fit to
the engine.
Note:
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.
