Throttle slide
With an opening of the throttle slide between 1/8 and 1/2, the
dimension on the projection of the slide influences the
mixture which, during this transition period from low to high
speed, must be relatively rich.
Main jet
The main jet of the carburetor has been selected for a
temperature of -20°C (O°F), at sea level. Other main jets can
be installed depending on temperature and/or altitude
differences. Always refer to spark plug electrode colour
and/or the piston crown to determine the appropriate jet size
to be used.
Adjustment of float level
In order for the engine to deliver its full power, it is essential
that the level of the fuel in the carburetor bowl remain at a
pre-determined level. To verify the proper float level, proceed
as follows:
o
Remove the carburetor bowl and gasket.
o
Turn the carburetor upside down, and measure the
height H between the seat of the bowl and the upper
end of the float lever.
o
Bend the stop flap of the float lever until the
recommended height has been reached.
o
The measured height H must be 23.9 mm
± 1 mm
(0.941" ± 0.040").
