Checking Spark Plug

c CAUTION: Avoid injury! Touching hot surfaces can burn skin. The engine and components will be hot if the engine has been running. Allow the engine to cool before servicing.

Check spark plugs at the intervals recommended in the Service Intervals section. See the engine manufacturer’s owner’s manual provided with your machine for the complete procedure.

Adjusting Carburetor - Carbureted Engines

NOTE: Carburetor is calibrated by the engine manufacturer and is not adjustable.

If engine is operated at altitudes above 1829 m (6000 ft), some carburetors may require a special high altitude main jet.

If engine is hard to start or runs rough, see Troubleshooting section of this manual.

Possible engine surging will occur at high throttle with transmission in neutral and mower disengaged. This is a normal condition due to the emission control system.

After performing checks in Troubleshooting section and your engine is still not performing correctly, contact the local engine manufacturer’s authorized servicing dealer.
