THROTTLE OVERRIDE SYSTEM (T.O.R.S.)
If the carburetor or throttle cable should malfunc-
tion 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.
