/ 



IMPORTANT! 

Read these instructions carefully before operating this Engine 
for the first time. 

Guessing how to run it, may cause you unnecessary inconvenience, 
aggravation, or failure to receive the fine service that is built into it. 

There is a right way to operate this Engine. This book tells 
you how. 

Each Engine is carefully tested and adjusted at the factory before 
packing for shipment, and if correctly operated will perform beyond 
your expectations. 

DO NOT START THIS ENGINE UNTIL YOU HAVE READ 
CAREFULLY THE INSTRUCTIONS ON PREPARING THE 
ENGINE, PAGE 3. 

For Maintenance Adjustments, see pages 6 to 9. 

If you have difficulty in operating your engine and you need outside help, 
contact your dealer or nearest member of our Authorized Service Organization. 
See back cover. 

Briggs & Stratton manufactured only the engine on your powered equipment. 
For other service or parts, write to the manufacturer of the complete equipment 
or see the dealer from whom purchased. 

CAUTION ! 



1. PROVIDE EFFICIENT VENTILATION. Exhaust gases 
contain carbon monoxide which is odorless and a deadly poison. 
Proper care must be taken to provide efficient ventilation. 

2. DO NOT FILL GASOLINE TANK WHILE ENGINE 

IS RUNNING. Avoid spilling gasoline on a hot engine — 
this may cause an explosion and serious injury. 

3. KEEP ENGINE CLEAN. This engine is air-cooled. If cool- 
ing system becomes clogged, serious damage may result. There- 
fore, keep the blower screen, fins on flywheel, cylinder head and 
block free from grass or dirt. 



GENERAL INFORMATION 

This engine is a single cylinder, L-Head air-cooled type; bore 2%e" and stroke 
\Vl". It is rated at: 

1.28 H.P. at 2200 R.P.M. 1.90 H.P. at 3200 R.P.M. 

1.71 H.P. at 2800 R.P.M. 2.00 H.P. at 3600 R.P.M. 

The horsepower ratings listed above are established by standard I.CJE.I. pro- 
cedures. For practical operation, the horsepower loading should not exceed 
85 per cent of these ratings. Engine power will decrease 3Vi per cent for each 
1,000 feet above sea level, and 1 per cent for each 10 degrees above 60 degrees F.

PREPARATION OF ENGINE 
BEFORE STARTING 



Fill Oil Sump With OH 

Remove the oil filler plug located on the 
base of the oil sump. Use screwdriver 
oi bar. 





Place the engine level. Pour oil in the 
opening until it rises to the top of the 
filler opening. Replace the filler plug. 
Screw it down tight. 



For temperatures 32° and above use Mobiloil Arctic (S.A.E. No. 20) or equal. 
For temperatures below 32° use Mobiloil 10W (S.A.E. No. 10W) or equal. 



Put Oil In Air Cleaner 



Air cleaner protects engine from 
grit and dirt. Use the same oil 
as in the crankcase. Remove 
wing nut. Lift out filter element. 
Pour in oil to "oil level" mark 
at end of arrows. Replace ele- 
ment and wing nut. Be sure 
gaskets are in place. See inset. 




Fill Fuel Tank 

Use a good grade of regular, clean, fresh gasoline such as Mobilgas. Never use gasoline 
that has been standing in a can for several months as gum may form under such conditions 
and clog the carburetor, fuel tank, etc. See that vent hole in cap is open. DO NOT 
MIX OIL WITH GASOLINE. 



USING THE ENGINE 



To Start Engine 

1. Be Sure the Stop Switch Is 
Away front Spark Plug

STORAGE INSTRUCTIONS 



Engines stored any length of time should 
be completely drained of fuel to prevent 
gum deposits forming on essential parts 
such as the carburetor, fuel filter, fuel 
lines, and tank. 

Such deposits may affect the operation of 
the engine when again used. Therefore, 
it is important that the following instruc- 
tions be adhered to before storing the 
engine: 

a. Remove fuel tank drain plug. Open 
fuel valve. Drain tank completely. 

b. Operate engine until it stops from 



exhaustion of fuel to clean gasoline out 
of carburetor. 

c. While the engine is still warm, drain 
and clean the crankcase. Refill with fresh 
oil. 

d. Replace fuel tank drain plug. 

e. Leave fuel valve open. 

f. Remove spark plug, pour one ounce 
of S.A.E. No. 20 oil into cylinder and 
crank slowly to spread oil. Replace 
spark plug. 

g. Clean dirt and chaff from cylinder and 
cylinder head fins, blower housing, etc. 






MAINTENANCE ADJUSTMENTS 

Draining Fuel Tank and Cleaning Fuel Filter 




1. Close Fuel Valve 



2. Remove Fuel 
Tank Drain Plug 



3* Detach Fuel Pipe 




4. Remove Fuel Filter 
From Fuel Tank 

Carburetor Adjustments 

Close the needle valve. Now 
open it IVi turns. Close the 
idle valve. Open it VS to 
% turn. Start engine and 
allow it to warm up. 

Turn needle valve in until 
engine misses, then turn it 
out past smooth operating 
point until engine runs un- 
evenly. Now turn needle 
valve in just far enough so 
engine runs smoothly. 



5. Clean With Gasoline. 
Screen Not Removable. 
Replace Filter, Pipe Plug, 
and Fuel Line. 




\ 



Set idle speed adjusting screw 
until engine idles at 1750 R.P.M. Hold throttle in idle position. Turn idle valve in or 
out until engine picks up speed and runs smoothly. Then again reset idle speed adjusting 
screw to bring engine to 1750 R.P.M. idling speed. Release throttle. Engine should 
accelerate without hesitation or sputtering. If it does not accelerate properly, the 
needle valve should be reset, usually to a richer mixture.

MAINTENANCE ADJUSTMENTS 

Governor Adjustments 

The correct operating speed range is 2600 to 3600 R.P.M. The standard speed setting 
(no load) is 3300 R.P.M. Idle speed is 1750 R.P.M. 

SPEED CONTROL 

There are two different types of speed controls on these engines. 

1 . Control Lever Mounted On 
Cylinder 

To change speed of engine loosen screw 
holding governor control lever. Move 
lever to the RIGHT to increase speed 
and to the LEFT to decrease speed. 
Tighten screw. Governor link should al- 
ways be in hole No. 4 of the throttle 
lever of carburetor. Spring should be in 
hole No. 1 of throttle lever. 

2. Hand Governor Control 

To change speed of engine move lever to 
the LEFT to increase speed and to the 
RIGHT to decrease speed. Governor link 
should always be in hole No. 4 and spring 
in hole No. 1 of throttle lever on carbu- 
retor. 

Remote Governor Confrof 

Engine speed is controlled by movement 
of the control lever as shown. Move re- 
mote control lever to HIGH speed posi- 
tion. Loosen screw on swivel. Move wire 
through swivel until desired operating 
speed is obtained. Retighten swivel screw, 
bend loose end of wire around swivel. 
Cut off excess wire. 



To Check Spark Plug Gap 

Spark plug is 14mm (USE CHAMPION 
J-8 OR EQUIVALENT). Keep a fresh 
plug on hand. Clean and reset the gap 
at .025" every 100 hours of operation. 
Use some graphite grease on threads when 
replacing spark plug. 






MAINTENANCE ADJUSTMENTS 



To Adjust and Clean Contact Points 




LEFT HAND 
THREAD 



To Remove Flywheel 

Rope Starter 

Remove the blower housing. Bolt or 
clamp the engine to a workbench. Hold 
the power take-off end of crankshaft to 
prevent rotation, or use Flywheel Holder 
61741-T19. Use a large wrench 10" or 
longer. Turn the nut to the RIGHT until 
loosened. 

Recoil Starters 

Same as above, except turn clutch housing 
to left. (Right-hand thread.) 

Never Try to Pry Off Flywheel 

After removing nut, washer and pulley, 
loosen flywheel by using Flywheel Puller 
No. 293596. Pull off flywheel. Save key. 

To Remove Flywheel With Flywheel Puller 



Blower housing, flywheel, and 
magneto point dust cover 
must be removed. Points 
must be clean and line up 
squarely to make good con- 
tact. Do not file points — use 
fine sandpaper or hone to 
dress the points. Turn the 
crankshaft until points open 
to widest gap, or until keyway 
on crankshaft lines up with 
the plunger. Tighten the con- 
denser clamp screw. Move 
condenser forward or back- 
ward with screwdriver until 
gap of .020" is obtained. If 
either or both points become 
badly pitted or burned, replace 
with complete new Contact 
Point Bracket and Condenser. 




HOLD POWER TAKE-OFF 
END OF CRANKSHAFT 




Screw the nut back on shaft until it is 
flush with threads. Fasten flywheel puller 
to flywheel by screwing two self-tapping 
screws into holes provided in flywheel. 
Turn down the two nuts gradually until 
flywheel is loosened. Pull off flywheel. 
Save key. 



MAINTENANCE ADJUSTMENTS (Cont'd) 
To Reassemble Flywheel 

Clean flywheel hole and tapered end of crankshaft thoroughly. Place flywheel on 
crankshaft and align keyways. Insert and push it securely into place. If key is 
partially sheared or damaged replace with a new key (Part No. 61760). This is a soft 
metal key. Do not use steel key. Assemble pulley and spring washer with the hollow 
side next to pulley. Put on nut. Hold power take-off end of crankshaft and draw nut 
up tight with a wrench. Replace blower housing.

HOW TO FIND THE CORRECT NUMBER 
OF THE PART YOU NEED 

a. Make a note of your engine MODEL AND TYPE NUMBER (not the Serial 
number) that appears on the metal nameplate attached to blower housing. 

b. Refer to pages illustrating parts and locate the Master Part Number by com- 
paring your old part with illustrations. Assemblies include all part numbers shown 
in frames in illustration. All parts shown in assembly frames on which part 
numbers are given can be purchased separately. 

c. After the Master Part Number has been identified, refer to the following 
Parts List where these Master Part Numbers are listed in numerical order. 
THE MASTER PART IS USED ON ALL TYPES OF ENGINES EXCEPT 
THOSE TYPES LISTED UNDER "NOTE." 

d. If a "Note" appears below the Master Part Number, this means that this 
part is made differently from the Master Part for certain types, and if your type 
is listed under "Note" order the part referred to. 

e. If your Engine Type Number does not appear after any part number listed 
under "Note," order the Master Part Number. 

f. When ordering parts — or writing for service information — always specify 
the MODEL NUMBER — TYPE NUMBER — and SERIAL NUMBER of your 
engine. 

g. All parts should be ordered from the nearest member of our Nation-wide 
Service Organization. (See back cover.) In ordering parts by mail, selling 
prices will be furnished on request or parts will be shipped at prevailing prices.
