Replacing the throttle cable
Only applies to model AR25.
1. Measure the length of the cable that extends
past the cable screw before disconnecting the
cable.
2. Remove the old throttle cable and insert a new
one through the guide hole on the back of the
cowling.
3. Insert the new cable through the cable screw
the same distance as the old one (see step 1)
and tighten the screw. This measurement is only
approximate and may require adjustment. See
the section above ”Adjusting the throttle cable”
to adjust the throttle settings.
4. Fit the new adjustable mounting (see the lower
illustration) on the spring on the throttle/clutch.
IMPORTANT INFORMATION
As the cable length increases between the
cable screw and the adjustment nut, the
engine speed decreases. If engine speed is
too low, the engine will stall when the clutch
is released. As the cable length decreases
between the cable screw and the adjustment
nut, the engine speed increases. If engine
speed is too high, you lose your ability to
start moving under control.
Adjusting the throttle cable
Only applies to model AR25.
1. Start the engine and allow it to reach operating
temperature.
2. Adjust the throttle cable at the adjustable
mounting (the left in the illustration) by turning
the adjustment nut. The tighter the setting, the
higher the engine speed. Undoing the nut
reduces engine speed.
IMPORTANT INFORMATION
If the throttle is properly adjusted, engine
speed increases somewhat when the clutch is
released.
• If the clutch is released too early, the engine
stalls.
• If engine speed is too high, you lose your
ability to start moving gradually and under
control.
