BELT TENSION ADJUSTMENT—Drive and Tii le
Clutches
Periodic adjustment of the belt tension may be reqi lired
due to normal stretch and wear on the belt. Adjusti nent
is needed if the tines seem to hesitate while tilling, but
the engine maintains the same speed.
To adjust, loosen the hex nuts at the cable bracki it on
the handle. See figure 18. With the clutch lever re­
leased as shown in figure 12, adjust the bottom n
Jt
so
that there is only a slight amount of slack in the co itrol
wire. Tighten the upper nut against the bracket.
NOTE
Do not overtighten control wire. Too
much tension may cause it to break.
CARBURETOR ADJUSTMENT
AC
WARNING
If any adjustments are made to the
engine while the engine is running,
(e.g.
carburetor), disengage all
clutches and tines. Keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude or load. If adjustments are needed, refer to
the engine manual packed with the tiller.
■^NOTE
A dirty air cleaner will cause engine to
run rough. Be certain air cleaner is
clean and attached to the carburetor
before adjusting carburetor. Do not make
unnecessary adjustments. Factory
settings are satisfactory for most appli­
cations and conditions.
THROTTLE CONTROL ADJUSTMENT
To obtain satisfactory engine performance, the engine
throttle control must be adjusted properly. If it is
necessary to check the engine control adjustments,
proceed as follows.
1. Loosen the cable clamp screw. See figure 19.
2. With the throttle control in FAST position (see
figure 12) and the cable connected to the adaptor
lever, push the cable through the cable clamp in
the direction shown in figure 19 until the adaptor
lever is as far up as it will go.
3. Tighten the cable clamp screw.
4. Check that the engine stops when throttle control
is moved to STOP position. If engine does not stop,
loosen cable clamp screw and readjust by pulling
cable backward slightly until engine stops.
Retighten cable clamp screw.
