THROTTLE OVERRIDE SYSTEM (T.O.R.S.)
If the carburetor or throttle cable should malfunction
during operation, T.O.R.S. will operate when the
throttle lever is released.
T.O.R.S. is designed to interrupt the ignition and keep
the engine revolutions between 2,800 and 3,000
r/min if the carburetor fails to return to idle when the
lever is released.
WARNING
•
If T.O.R.S. operates, make sure that the cause
of the malfunction is corrected and that the
engine can be operated without a problem
before restarting the engine.
•
Be sure to use the standard resistance-type
spark plug and spark plug cap. Otherwise,
T.O.R.S. will not work properly.
