SPARK PLUG:
1. Remove the spark each time you change the
oil and inspect it. See figure 32.
A. The electrodes should be kept clean and
free OF CARBON. The presence of carbon
or excess oil will greatly deter proper
engine performance.
B. If possible, check the spark plug gap (area
between electrodes) using a wire feeler
gauge. This specification should be .030.
2. If you need a spark plug refer to the parts list
for the proper replacement spark plug.

STORAGE:
If the tiller is not to be used for a while, the fol­
lowing procedure should be followed. The tines,
drag stake, transmission, and wheels should be
cleaned of all dirt. It is very important that the unit
be stored in a level position to prevent engine oil
from draining into the cylinder head cavity.
Engines on tillers to be stored between season
should be completely drained of fuel to prevent
gum deposits forming on essential carburetor
parts, and fuel tank.
(a) All fuel should be removed from fuel tank.
Run the engine until it stops from lack of
fuel. The small amount of fuel that remains
in the sump of the tank should then be
removed by absorbing it with a clean dry
cloth.
(b) Clean dirt and chaff from cylinder, cylinder
head fins and blower housing.
(c) Remove spark plug, pour 1 ounce (2 or 3
tablespoons) of S.A.E.-30 oil into cylinder
and puli crank cord out slowly to distribute
oil. Replace spark plug.
Just as your automobile needs professional
mechanical maintenance from time to time, so
does your air cooled engine. Cleaning and adjust­
ing of the carburetor and periodic replacement of
the spark plug and ignition points is made neces­
sary by NORMAL use.
Professional Air Cooled Engine Service is as close
as your nearest SEARS SERVICE DEPARTMENT.
A yearly check-up or tune-up by Sears is a good
idea to avoid breakdov/ns or delay ... do it at the
end of the season, then you’re ready for the next.
