Make sure fuel tank, fuel filters and fuel lines are
clean. Reinstall carburetor, replacing any worn or
damaged governor springs or linkage. Make proper
governor adjustment. Adjustments are found in the
manual under governor linkage and adjustment and
engine reassembly.
4. Replace with correct spark plug.
5. Make sure all ignition wires are properly routed, so
they will not rub on flywheel. Inspect all ignition wires
for abrasion or damage. Remove flywheel and
check flywheel key, reinstall flywheel, torque
flywheel nut to specifications. Set air gap between
solid state module and flywheel at .0125'. Air gap
gauge, part no. 670297 may be used.
6. The engine must be firmly mounted to the associated
equipment. On rotary lawnmowers, make sure blade
is properly balanced and correctly torqued. See
dissassembly section for flywheel removal and air
gap setting procedure.
7. Make sure all remote linkage is properly adjusted
for proper operation.
8. Fill tank with proper fuel/oil mix.
9. Run the engine, allow it to warm up 5 minutes, then
adjust carburetor and set R.P.M. according to
Tecumsehs recommendations.

EXHAUST PORT CLEANING.
The exhaust ports
should be cleaned after each seventy-five (75) to one
hundred (100) hours of use.
Before cleaning the ports place the piston in the Bottom
Dead Center position. Then clean the ports using a
pointed 3/8' diameter wooden dowel or similar tool. Be
sure not to scratch the port area. Also remember to
remove all the loose carbon particles from the engine.

STORAGE:
NEVER STORE ENGINE WITH FUEL IN TANK
INDOORS OR IN ENCLOSED, POORLY
VENTILATED ENCLOSURES WHERE FUEL
FUMES MAY REACH AN OPEN FLAME, SPARK
OR PILOT LIGHT AS ON A FURNACE, WATER
HEATER, CLOTHES DRYER, ETC.
If engine is to be stored over 30 days, prepare for storage
as follows:
1. Remove all gasoline from fuel tank to prevent gum
deposits from forming in tank and other fuel system
components, causing possible malfunction of the
engine.
DRAIN FUEL INTO APPROVED CONTAINER
OUTDOORS, AWAY FROM OPEN FLAMES.
Run engine until fuel tank is empty and engine stops
due to lack of fuel.
Fuel stabilizer (such as STA-BIL) is an acceptable
alternative in minimizing the formation of fuel gum
deposits during storage. Add stabilizer to fuel in fuel
tank or storage container. Always follow mix ratio
found on stabilizer container. Run engine at least
10 minutes after adding stabilizer to allow it to reach
carburetor.
If gasohol has been used, complete preceding
instructions and then add a small amount, one pint
or less, of unleaded regular automotive gasoline
properly mixed with the specified lubricating oil and
run the engine until the fuel tank is empty and the
engine stops due to lack of fuel.
2. Pull starter handle slowly until resistance is felt due
to compression pressure, then stop. Release starter
tension slowly to prevent engine from reversing due
to compression pressure. This position will close
both the intake and exhaust ports to prevent
corrosion of the piston and the cylinder bore.
3. Clean unit by removing any dirt from exterior of the
engine and equipment.
TUNE-UP PROCEDURE.
The following is a minor tune-
up procedure. Repair procedures for this engine and
its components are listed in this manual if the engine
does not perform to satisfaction after tune-up is
performed.
CAUTION:
Remove spark plug wire before doing
any service work on engine.
1. Service or replace air cleaner as necessary.
NOTE:
Snow King

engines do not use an air filter
due to the clean operating environment and to
prevent filter freeze-up.
2. Remove blower housing, clean all dirt, grass or
debris from air intake screen, cylinder cooling fins,
and carburetor governor levers and linkage.
3. Remove carburetor, clean and install a carburetor
kit, make adjustment presets where needed. Presets
are found in the carburetor section of this manual.
