A
regulator may be
blamed for
an underc
harged
or repeatedly
discharged
battery when the fault is
actually self-discharge caused by a
build-up
of corrosive acid across the
top
of the
battery.
Even a
light coating of this grayish-white substance
can
complete a ci r cui t to drain
and exhaust
the energy in
the battery--this can be especially bad when moisture
i
s present
.
Service as

To maintain a battery in top condition

check and perform

services at

1
.
Regularly check
l
evel of electrolyte--add water as necessary to maintain
level
above plates
--do
not
overfill as this can
cause
poor performance or early failure due
t
o loss of
electrolyte
.
2. Keep terminals and top of battery clean
.
Wash with baking soda and rinse
with
clear water
.
Do
not
allow soda solution to enter cells as this will destroy the electrolyte.
starting motor
Precautions:
In the event of a "false start" (engine gets up sufficient
speed
to disengage starter but
fa1ls to ontinue running), the engine
must
be completely stopped before another starting attempt is
made
.
If the flywheel is still rotating, the drive pinion and ring gear will clash and be damaged.
Limit cranking (continuous) to a period of 30 seconds to prevent overheating of the starter.
If cranked
for 30 seconds, starter should not be operated again for 60 seconds to allow time for cooling.
Starting
m
ot or s do not require service at any specific intervals.
They are pre-lubricated during
manufacture and brushes normally require
attention
only after extensive use--see trouble analysis below.
Connections to starting motor should be checked occasionally to make sure they are tight and that leads
are in good
condition.
The following precautions should be observed on electric
start
models to prevent
starter damage and/or depletion of battery energy.
Trouble Analysis:
If starter fails to energize, first check wiring, starting switch or solenoid and
condition of battery.
Clean or replace badly corroded or dirty contacts--replace wires if frayed or
cracked.
Bypass start switch or solenoid with jumper wire--if starter cranks normally, replace defective
switch or solenoid.
If starter turns too slowly and battery is in good condition, check for dirty
brushes or commutator.
Further trouble analysis will require special test equipment available only at
authorized repair
stations.
Alignment:
Alignment of starter pinion to ring gear is established by the machined surface of starter
mounting flange on the side of the cylinder block and through special mounting bolts
.
To prevent mis
alignment and gear damage, make sure the proper shoulder bolts are used and that they are securely
tightened at all times.
carburetor adiustments
Carburetors are calibrated in the factory and the main fuel system cannot be reset.
If black exhaust
smoke is noted, check the air cleaner--an "overrich" mixture is usually caused by a poorly serviced,
clogged air cleaner element.
If idle readjustment becomes necessary, stop the engine, then turn the IDLE fuel adjusting screw,
all the way in until it bottoms lightly--don't force it closed as this will damage the needle valve.
For preliminary settulg, turn the IDLE 1-1/4 turn out
.
For final adjustments, start engine and allow it
to warm.
The IDLE fuel can then be set by turning the adjustment in until the engine slows down.
Now
turn the screw out--the engine will regain speed at first and then it will slow down-
-note
the positions
of screw at both settings
,
then set it about half way between the
two.
governor adiustments
The governor functions to maintain engine speed under changing load conditions and also acts as a
speed limiting device
.
Governors are set in the factory and further
adjustments
should not be required
unless linkage works loose or becomes disconnected.
Readjustment
should be made if
t
he engine surges with
changing load or if speed drops considerably when a normal load is applied.
Readjustment should
be
m
ade
by a
qualified
person only
.
