RETRACTABLE STARTERS
Retractable starters are lubricated during manufac-
ture and should require no further lubrication until
disassembly for cord or rewind spring replacement
or for other repair.
Frequently check mounting screws to make sure
starter is securely tightened on blower housing of
engine. If screws are loose, starter realignment
may be necessary. Also make sure that the air
intake screen is maintained in clean condition at all
times.
MODEL K91
FAIRBANKS-MORSE STARTERS
Starters have die cast aluminum housings. A fric-
tion shoe assembly under spring tension is used
and engages in the drive cup when the starter
handle is pulled. The drive cup is held in place on
the engine with the flywheel nut. A pin on the cup
is engaged in crankshaft keyway to prevent slip-
page of the drive cup.
Refer to Figure 7-1 .

Operation
1 . Be sure starter screen is kept clean when op-
erating engine or serious engine damage can
result from lack of cooling air.
2.
After engine has started, do not allow starter
rope to snap back into starter housing. Con-
tinue to hold handle and allow starter rope to
rewind slowly.
NOTE: Releasing handle when starter rope is ex-
tended will shorten life of starter.
3.
Do not use starter in a rough manner, such as
jerking or pulling starter rope all the way out.
A smooth, steady pull will start engine under
normal conditions.
4.
Always pull starter handle straight out so that
rope will not receive excessive wear from fric-
tion against guide. Proper procedure will pre-
vent unnecessary wear.
5.
If recoil starter should ever fail, starter assem-
bly can be removed and engine cranked with a
rope. The starter drive cup will serve as a pul-
ley for emergency purposes.
