MAINTENANCE 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. 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. 8011-163 8011-250 8011-118 English - 27
