OPERATOR’S MANUAL
Idling adjusting
When adjusting idle speed on twin carburettor models, repeat on
the other one.
· Gas wire adjusting: Screw down the gas wire with adjusting
screw so that there is no slack between the mantel of the gas
wire and adjusting screw. Then unscrew it 1/2 rounds (the
slack will be 1 mm) and lock the adjusting screw with the
nut.
· Air screw basic adjustment: Screw down the air screw carefully
and unscrew then 1 round.
· Idling basic adjustment: Turn the idling screw clockwise until
it contacts throttle.
Turn two rounds still. Now the idling is roughly adjusted.
· Check the injection oil pump adjustment.
· Start the engine and let it warm up to the normal using
temperature.
· Then adjust idling with set screw fast idling.
· Adjust with the air screw ( the area 3/4...1 1/5 ) most even
running.
· Unscrew idle speed screw to obtain the normal idling speed
1800—2000 rpm.
NOTE: You must not drive with the snowmobile if the intake
silencer is removed, the fuel mixture becomes too lean.
