BREAKER PO I NT S: Points are und er the rec tangu lar cover on th e carburet or side of eng ine. Use the fol lowing
procedure to a
djust breaker point gap:
1.
Re mo ve brea ker po in t cov er.
2. Turn engine o ver unt il breaker point s ar e full open--measure gap with feele r gauge. Ope ni ng
should be .020" . Adj
ust by loosening gap adjusting screw then ins ert screwdr iver blade in
adjusting n ot ch to shi f t moveable plate unt il .020" opening is attained. Ret i ghten gap ad-
justing screw.
3.
Gap set t ing can vary (.017 - .023) . To achieve sm oo thest runn in g see timi ng light in st ruct ions
bel ow.
Alwa ys repla ce ba dly burned or pitt ed breaker points. A certain amoun t of bui ld up or me ta l transfer
occ urs under norma l operat ing conditio ns; however, if t his occurs too frequent l y and becomes excessi ve,
the condenser may be at fau lt . Slig htly p it te d points can be dress ed down with a point f ile, al though
thi s should be done only as a t emporary fix since p oints may tend to arc more readily after f il in g. Re-
place
points at fi rst o pportuni ty after filing . If points are oxidi zed, rub a piece of coarse clo th be-
tween the s
urfaces . Dirty or oi ly points can be cleaned with a cloth but make sure no parti cles of lint
are left between sur fa c es.
TIMING: Engines are equipped with a timing sigh t hole in either the bear ing plate or in the blower housing.
Two tI ming marks are st am ped on the flywheel --the T mark indicates Top Dead Center (TDC) while the S or
SP mark
indicates the Spark or Spark Run point which is 20° before TDC.
Two me thods can be used for tim ing--the t im in g l i ght me thod is the more precise way of achieving
exact t iming. The timing light can be used with ma gnet o ignition syste ms; however, a storage bat tery may
have
to be used per timing lig ht manu factu rer's instructions.
MET HOD 1 - S TATIC TTIMING: Remov e breaker point cover and remove spark plug lead to prevent unintentio nal
startIng. Rotate engIne by hand in direction of normal rotation (clockwise when viewed from blower housing
end).
Points should just beg in t o b reak as the S mark appears in the cen te r of the t iming s ight hole.
Continue
rotating engine unti l poin ts reach maxim um opening. Measure gap with feeler gauge--gap should
be .020"
fully open. If necessary, loosen point gap adjustment screw and readjust gap to .020" full open.
MaximlDll gap setting can vary a few t housandt hs (.017 - .023) to achieve smoothest running. Securely tighten
adjusting screw after timing.
METH OD 2 - TIMING LICJIT: Several different types of timing lights are available- -follow manufacturer 's
mst.ruct ions for type used. The fo ll ow in g t iming procedure can be used with ~ timing l ight s :
A.
Remove hi gh tensio n l ead at spark plug --wrap one end of a short piece of fine wire around spark plug
terminal. Reconnect l ead to terminal--free end of wire must protrude from under boot. (Note: Step
A
for t im in g l ights with alligator clips--some lights have sharp prongs on spark lead- -on these sim-
ply push prong thru boot until i t contac ts metal connector.)
B. Connect one timing l i ght lead to the w ire that has just been wrapped around spark plug termina l.
C. Connect second timing lignr-lead to hot (ungrounded) side of battery--see timing light instructions
for ba ttery size, wiring, etC:--
D. Connect third timing light lead to ground.
E. Rotate engine by hand
until S mark visible--chalk S line for easy reading.
F. Start engine, run at 1200 - 1800 RPM, aim timing light into sight hole --light should flash just as
S mark i s ce
ntered in sight hole or even with center mark on bearing plate or blower housing.
G. If timing is of f--re move breaker point cover, l oosen gap adjusting screw, shif t breaker plate until
S mark is exact ly centered. Retighten adjusting screw before replacing breaker po in t cover.
alternator system
On electric st ar t mode ls the IS amp al te rnator sys te m provides electr ica l energy t o charge t he battery.
A solid state recti f ie r-regulator is mo unte d ex ternally on the engine or on the equipment powered by the
engine. The system
al so inclu des an al ternator-s ta t or and permanent magne t ring in s ide the fl yw heel .
These systems
are vi r tu ally serv ic e free--the only requi red service is an occas ional check to make sure
t
hat all electrical connec tion s are t igllt and th at w ires are not frayed or cracked. Ch eck the precau tio ns
to
the system on your engine to avoid d ama g in g charging s yst em components.
PRECAUT IONS--lS AMP SYSTEM
1. Battery pola ri t y must be co rrect. Negat ive ground syst e ms are used with Koh le r Engines.
2. Prevent
altern ator lea ds (AC) from t ouch in g or short ing. Th is co uld permane ntly damage the s tator.
3. Disconnect leads at rectifi~r --regulat or be for e e lect ric welding is done on equipment in common
ground with engine.
4.
Do not operate for any length of t ime w it hout a bat tery in the syste m.
