4. Clean spark plug carefully with a wire brush.
· Pitted or damaged electrodes.
NOTE: In Canada, replace spark plug with resistor plug only.
6. Replace spark plug as necessary.
7. Check plug gap with a wire feeler gauge.
· Gap must be 1 mm (0.040 in).
· To change gap, move the outer electrode.
8. Install and tighten spark plug to:
Kohler Engine: 40 N·m (30 lb-ft.)
Briggs and Stratton Engine: 20 N·m (15 lb-ft.)
9. Connect spark plug wire and lower hood.
Adjusting Carburetor
NOTE: Carburetor is calibrated by the engine manufacturer and is not adjustable.
If engine is operated at altitudes above 1829 m (6,000 ft.), some carburetors may require a special high altitude main jet. See your John Deere 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 John Deere dealer.
