18 MAINTENANCE SECTION

b •. Remove cover and filter and pour out oil.

c. Wash the outside of the filter element with a rag or brush dipped in gasoline. Do Dot submerge.

. d. Clean bowl and cover by submerging in gasoline and wipe dry.

e. Replace parts. Fill cleaner with same oil as used in the crankcase up to the level marked on cleaner bowl. See instructions on air cleaner label.

MUFFLER 61. TO CLEAN. After long periods of service it is possible that the muffler will become clogged to the point where it will atrect the engine's power. To check the muffler unscrew it from the engine and run water into the open end of the muffler. If full streams of water come out of small holes at the end of' the mutrler, you will know that it is not clogged up. If the water runs through very slowly, however, the mutrler is probably clogged and should be replaced.

OVERLOAD 0. TO PREVENT.- Always be sure that the machine the engine Is operating is well lubricated and running freely. . If it is not, it may cause the engine to be overloaded, resulting in it overheating, losing power, or stopping entirely.

Starter Pedal Adjustment-Plate No. 25

STARTER PEOAL---4--+-

RETUlte SPRING CUP

63. STARTER PEDAL ADJUSTMENT.

Should the starter pedal return spring, on engines with the starter on the power take­off side, loosen or lose its tension, loosen the bolt which holds the return spring cup . See plate No. 25. Turn the cup to the left until there is just enough tension to return the starter pedal back to the normal posi­tion after depressing it, and tighten the bolt. Too much tension may cause spring to break. Be sure the spring is in the proper position. with the long end below the pedal adjusting bolt and the hooked end in the slot of the cup.

64. STARTER CLUTCH. If the starter clutch sUps or fails to turn the engine, when stepping on the starter pedal, it is probably caused by one of the following reasons:

Loose set screw. Worn clutch housing. Worn or broken pinion.

To correct this; proceed as follows:

a. Tighten the set screw to be sure dutch is tight on the crankshaft. Use f,;" Allen hexagon set screw wrench.

b. If the clutch still slips, loosen set screw and remove clutch from the shaft.

eo Pry out the snap spring with a sharp tool. holding the clutch in the position shown in plate No. 26. as a precaution against the spring jumping out. Check the parts carefully for wear or damage and replace those necessary.

d. To reassemble, replace the parts in the same order, and slip the spring back in place. Replace pulley clutch on shaft with the set screw hole lined up with recess in crankshaft extension. Securely tighten set screw.

Gil. HOW TO FIND THE CORRECT NUMBER OF THE PART YOU NEED

a. Make a Dote of your engine MODEL NUMBER (Not the Serial Number) that appears on the metal nameplate attached to cylinder shield.

b. Refer to pages Illustrating parts and locate the Master Part Number by comparing your old part with Illustrations. Assemblies include all pari numbers shown In frames In illustration. All paris shown In assembly frames on which pari numbers are given can be .purchased separately.

e' After the Master Pari Number has been IdentUled, 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."

Type numhers refer1'ed to under "Note" are the same as model num­hers with the first three figures (1'roO.) dropped.

d. If a "Note" appears below the Master Pari Number. this means that this part Is made different 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 pari num­ber listed under "Note." order the Master Part Number.

t. When ordering parts - or writing for servlee Information - al­ways specify the MODEL LETTER--TYPE NUMBER--and SERIAL NUMBER of your engine.

All parts should be ordered from our nearest store or mall order house.
