SPARK PLUG
Check the spark plug every 25 hours. Re-
place the spark plug if the electrodes are
pitted, burned, or if the porcelain is cracked.
1.
Make sure the spark plug is clean.
Clean the spark plug by carefully scrap-
ing the electrodes (do not sand blast or
use a wire brush).
2.
Check the spark plug gap with a feeler
gauge. The gap must be 0.030”.
3.
Before installing the spark plug, coat
the threads lightly with oil for easy re-
moval. Tighten the spark plug to a torque
of 15 foot-pounds.

SERVICE AND ADJUSTMENT
CARBURETOR ADJUSTMENT
Never make unnecessary adjustments to the
carburetor. The carburetor was set at the
factory to operate efficiently under most ap-
plications. However, if adjustments are re-
quired, we recommend you contact your
nearest
Ardisam
Service Center.
WARNING: The engine gover-
nor is set at the factory. Do not
change the governor setting.
Over speeding the engine above the fac-
tory setting can be dangerous. If you
think the engine governor needs an ad-
justment, contact your nearest
Ardisam
Service Center.
