RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit
performance. Be sure to use fresh, clean,
unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid damage to
the unit, do not mix oil with gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and
oxygenates such as ethanol, methanol or MTBE (ether).
Alcohol-blended fuel absorbs water. As little as 1% water in
the fuel can make fuel form acids when stored. When using
alcohol-blended fuel, use fresh fuel that is less than 60 days
old.
Using Blended Fuels
If you choose to use a blended fuel, or if its use is unavoidable,
follow recommended precautions:
• Always use fresh unleaded gasoline
• Use Sta-Bil®or an equivalent
• Drain tank and run the engine dry before storing unit
Using Fuel Additives
The use of fuel additives, such as Sta-Bil®or an equivalent,
will inhibit corrosion and minimize the formation of gum
deposits. Using a fuel additive can keep fuel from forming
harmful deposits in the carburetor for up to six (6) months. Add
0.8 oz. (23 ml.) of fuel additive per gallon of fuel to an approved
gas container according to the instructions on the container.
NEVER add fuel additives directly to the unit's gas tank.
FUELING THE UNIT
NOTE: Fill or add fuel to the tank only when the cultivator is in
a horizontal position (Fig. 9).
1. Remove fuel cap. Remove the tag from the fuel tank neck.
2. Place spout of gas container into the fill hole on the fuel
tank and fill tank.
NOTE: Do not overfill tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source
and site before starting the engine.
NOTE: Dispose of the old gasoline in accordance to Federal,
State and Local regulations.

Fuel Cap
OIL AND FUEL INFORMATION
WARNING: Gasoline is extremely flammable.
Ignited vapors may explode. Always stop the engine
and allow it to cool before filling the fuel tank. Do not
smoke while filling the tank. Keep sparks and open
flames at a distance from the area.
WARNING: Add fuel in a clean, well ventilated
outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilt fuel. Do
not start the engine until fuel vapors dissipate.
WARNING: Remove fuel cap slowly to avoid
injury from fuel spray. Never operate the unit without

The condition of the air filter is important to the operation of the unit.
A dirty air filter will restrict air flow. This is often mistaken for an out
of adjustment carburetor. Check the condition of the air filter before
adjusting the idle speed screw. Refer to Air Filter Maintenance.
Adjust Idle Speed Screw
If, after checking the fuel and cleaning the air filter, the engine
still will not idle, adjust the idle speed screw as follows:
1. Start the engine and let it run at a high idle for a minute to
warm up. Refer to Starting/Stopping Instructions.
NOTE: Ensure the tines are not in contact with the ground
when adjusting the idle.
2. Release the throttle trigger and let the engine idle. If the
engine stops, insert a small phillips or flat blade screwdriver
into the hole in the air filter/muffler cover (Fig. 22). Turn the
idle speed screw in, clockwise, 1/8 of a turn at a time (as
needed) until the engine idles smoothly.
Fig. 21
ROCKER ARM CLEARANCE
The rocker arm clearance may need adjustment if your unit
suffers a loss of performance power or has trouble starting.
Adjusting the rocker arm clearance requires disassembly of the
engine. If you feel unsure or unqualified to perform this, take
the unit to a Sears or other qualified service dealer.
NOTE: Inspect the valve to rocker arm clearance with a feeler
gauge after the first 10 hours of operation and then
every 25 hours of operation thereafter.
• The engine must be cold when checking or adjusting the
valve clearance.
• This task should be performed inside, in a clean, dust free area.
To adjust the rocker arm clearance:
1. Remove the two (2) screws on top of the engine cover with
a Flat-head or T-25 Torx screwdriver (Fig. 23).
2. Remove the screw behind the engine cover (Fig. 24).
3. Disconnect the spark plug wire.
4. Clean dirt from around the spark plug. Remove the spark

MAINTENANCE AND REPAIR INSTRUCTIONS
WARNING: This unit needs to run during idle
speed adjustment. Wear protective clothing and
observe all safety instructions to prevent serious
personal injury.
NOTE: The tines should not rotate when the engine idles.
3. If the tines rotate when the engine idles, turn the idle speed
screw counterclockwise 1/8 of a turn at a time (as needed),
to reduce idle speed.
Checking the fuel, cleaning the air filter, and adjusting the idle
speed should solve most engine problems. If not and all of the
following are true:
• the engine will not idle
• the engine hesitates or stalls on acceleration
• there is a loss of engine power
Have the carburetor adjusted by a MTD or other qualified
service dealer.

• Both rocker arms move freely, and both valves are closed
If these statements are not true, repeat this step.
8. Slide the feeler gauge between the rocker arm and the
valve return spring. Measure the clearance between the
valve stem and rocker arm (Fig. 29). Measure both the
intake and exhaust valves.
The recommended clearance for both intake and exhaust is
0.003 – 0.006 in. (0.076 – 0.152 mm). Use a standard automotive
0.005 in. (0.127 mm) feeler gauge. The feeler gauge should slide
between the rocker arm and valve stem with a slight amount of
resistance, without binding. See Figure 28 and 29.
9. If the clearance is not within specification:
a. Turn the adjusting nut using a 5/16 inch (8 mm) wrench or
nut driver (Fig. 29).
• To increase clearance, turn the adjusting nut
counterclockwise.
• To decrease clearance, turn the adjusting nut clockwise.
b. Recheck both clearances, and adjust as necessary.
10. Reinstall the rocker arm cover using a new gasket. Torque
the screw to 20–30 in•lb (2.2–3.4 N•m).
11. Reinstall the engine cover. Check alignment of the cover
before tightening the screws. Tighten screws.
12. Check the spark plug and reinstall. See Replacing the
Spark Plug.
13. Replace the spark plug wire.

REPLACING THE SPARK PLUG
Use a replacement 791-180852B spark plug. The correct air
gap is 0.025 in. (0.635 mm.). Remove the plug after every 25
hours of operation and check its condition.
1. Stop the engine and allow it to cool. Grasp the plug wire
firmly and pull the cap from the spark plug.
2. Clean dirt from around the spark plug. Remove the spark
plug from the cylinder head by turning it counterclockwise
with a 5/8” socket.
3. Replace cracked, fouled or dirty spark plug. Set the air gap at
0.025 in. (0.635 mm.) using a feeler gauge (Fig. 23).
4. Install a correctly-gapped spark plug in the cylinder head.
Turn the 5/8 in. socket clockwise until snug.
If using a torque wrench torque to:
110-120 in.•lb. (12.3-13.5 N•m)
