3. NEVER TAMPER WITH ENGINE GOVERNOR
WHICH IS FACTORY SET FOR PROPER
ENGINE SPEED. OVERSPEEDING ENGINE
ABOVE FACTORY HIGH SPEED SETTING
CAN BE DANGEROUS. IF YOU THINK THE
ENGINE GOVERNED HIGH SPEED NEEDS
ADJUSTING, CONTACT YOUR NEAREST
AUTHORIZED SEARS SERVICE CENTER,
WHO HAS THE PROPER EQUIPMENT AND
EXPERIENCE TO MAKE ANY NECESSARY
ADJUSTMENTS.
SPARKPLUG:
1. Remove the spark plug each time you change
the oil and inspect it. See figure 38.
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 yellow
pages of your phone book under “Engines Gas­
oline" for an authorized dealer.
If the tiller is not to be used for a while, the
following procedure should be followed. The
tines, depth bar, 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 seasons
should be completely drained of fuel to prevent
gum deposits forming on essential carburetor
parts, and fuel tank.
TILLER INSTRUCTIONS FOR WINTER
OPERATION (under 40*F.)
Engine Lubrication. Drain the summer engine oil
while engine is warm. Refill with new “winter
grade” oil. Run engine until warm to distribute the
new winter oil.
Use oil “for service” SC, SD, or SE. Use 5W-20 or
5W-30. If not available, use 10W, or 10W-30.
Fuel. Replace any summer gasoline on hand or in
the fuel tank with fresh winter-grade gasoline. Use
lead-free or leaded “regular” grade automotive
gasoline. Winter fuels have additives for faster
starting. Keep fuel tank full.
NOTE
Many automotive gasolines no long­
er contain “de-icer.” A can of gas­
line de-icer fluid added to yourgaso-
line supply will help maintain the
engine’s winter reliability.
Cold Starting Hints
1. Be sure to use proper winter-grade oil and
gasoline.
2. Declutch all possible external loads.
3. Set governor control at low-speed position.
4. Turn carburetor needle valve approximately
1 /8 turn counterclockwise. (Richer fuel
mixture) This will improve cold weather
starting and operation.
