Engine Warranty Maintenance Statement
Maintenance, repair, or replacement of the emission control devices and systems on this engine, which are being done at the customers expense, may be performed by any nonroad engine repair establishment or individual. Warranty repairs must be performed by an authorized John Deere dealer.
Adjusting Carburetor
NOTE: The carburetor is calibrated by the engine manufacturer and should not require any adjustments.
NOTE: 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.
NOTE: Possible engine surging will occur at high rpm when the transmission is in neutral ("N") and the PTO switch is in the OFF position. This is a normal condition due to the emission control system.
