General Information
Your carburetor comes from the factory
with a standard setting.
This setting provides an optimum fuel-air
mixture under most operating
conditions.
It ensures your machine will deliver
maximum power, be fuel efficient and
operate reliably.
If the setting is too lean there is
a risk of engine damage due to
insufficient lubrication and
overheating.
Standard Setting
: Shut off the engine.
: Remove the auger.

necessary.
: Carefully screw both screws down
onto their seats.
: Open the high speed screw (H) one
full turn.

full turn.
