screen and other external surfaces of the engine, including
cooling fins, clean at all times to allow adequate air intake.
Keep air intake screens and engine cooling fins clear of debris to
ensure proper cooling. See the engine manufacturer's owner's
manual provided with your machine for the complete procedure.

carburetors may require a special high altitude main jet. See your
authorized dealer.
If engine is hard to start or runs rough, check the
TROUBLESHOOTING section of this manual.
Possible engine surging will occur at high throttle with transmission
in "N" neutral and mower engagement lever disengaged. This is a
normal condition due to the emission control system.
After performing the checks in the troubleshooting section and your
engine is still not performing correctly, contact your authorized
dealer.
