INSTALLATION OF THE CARBURETOR
Retainer Nut
Carburetor Rubber
Gasket
0.2mm gap
Loosen the retainer nut, press the carburetor well
down into the intake boss, compressing the rubber
gasket as shown in the sketch, before re-tightening
Nut.
Rotate the retainer nut gently until it stops, then
tighten a further 90-120 degrees. Do not over-
tighten the screw as this will damage the carburetor
body.

Press down until the gasket becomes almost invisible.
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.
