EPA (US Environmental Protection Agency) regulations require tamper

proof carburetors to assure engines maintain exhaust emission

compliance. Carburetor service and high altitude adjustments can be

made by Authorized Service Centers or Factory Service Centers.

Replacing carburetors: Carburetor service requiring full carburetor replacement –

confirm H and L needles are set to factory settings.

Consult the appropriate repair manual and/or operator’s manuals for the proper carburetor

settings for a specific machine.
