CARBURETOR
If the carburetor needs readjustment, open the carburetor
MAIN JET ADJUSTMENT needle valve approximately 2
full turns from its seat. After the engine is started and
warmed up, adjust the needle valve for best operation under
full load, if possible. In cold weather, starting may be
facilitated by opening the needle valve slightly more, then
readjusting to normal running position after engine is
started.
Figure 15
The correct amount of throttle plate opening for the proper
low idle speed is obtained by means of the THROTTLE
STOP SCREW. However, this is set at the factory so that no
further adjustment is necessary. The IDLE ADJUSTMENT
is for smooth low speed operation and this adjustment, if
necessary, must be made with the carburetor throttle lever
closed. Initial setting is approximately 1-1 /2 turns.
TIMING
No timing adjustment or breaker point setting is necessary.
All solid state components are neatly molded into the
stator which is mounted to the flywheel end bearing plate.
The only mechanically moving part is the magnetic rotor, a
component part of the flywheel.
STARTER-GENERATOR DRIVE BELT
To check generator belt for proper tension stop engine. Belt
should depress 1/4 inch between pulleys with normal
thumb pressure as shown in Figure 16. Should adjustment
be required, loosen the two lower generator mounting
screws "B" and generator adjusting screw "A." Pivot
generator outward from engine until proper tension is
obtained.
NOTE: NEVER PRY OUT GENERATOR WITH A LONG
HEAVY BAR OR TOOL AS THIS WOULD RE-
SULT IN PREMATURE BEARING FAILURE.
Tighten the generator adjusting screw "A" and generator
mounting screws "B ." Make sure
all bolts and nuts are
securely tightened.

P.T.O. BELT - ADJUSTMENT
The P.T.O. belts can be adjusted by loosening the three cap-
screws that hold P.T.O. support casting to axle support
casting. Raise or lower P.T.O. support casting to obtain
proper adjustment.
When P.T.O. levers are 1-1/8 to 1·1/4 inches from the rear
of quadrant the P.T.O. belt should start to tighten.
If belts are properly adjusted (as described above) and still
drag, check adjustment of lower belt guide. There should be
not more than 1/8" clearance between pulley and belt
guide all the way around when P.T.O. is engaged but should
not rest on the belt at any point when running.
