SERVICE ENGINE
Checking Spark Plug 
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.
