Maintenance

CARBURETOR

The carburetor is adjusted at the
factory. It should not need to be
reset. If black exhaust is noted,
check the air cleaner first. An
over-rich mixture is usually caused
by a poorly serviced or clogged air
cleaner element, not an improperly
adjusted carburetor. If readjust-
ment is necessary, refer to engine
owner's manual or contact your
engine dealer.

ENGINE STORAGE

If engine will be unused for 30
days or more, prepare it for stor-
age by following the recom-
mended procedures found in the
engine owner's manual.
TIP: Before tipping mower, install
a small plastic sandwich style bag
under the gas cap and tighten se-
curely. This will virtually elimi-
nate any fuel weepage from the
cap. Be sure to remove the plastic
bag before re-using mower.
