Engine Idle Speed; Idle Speed Adjustment - Honda TRX300EX Owner's Manual

Engine Idle Speed

The best way to assure proper carburetion is to see your Honda dealer
for regularly scheduled servicing, including carburetor adjustment.
Remember, idle speed adjustment is not a ''cure-all'' for other problems
in your engine's fuel-delivery system. Adjusting the idle will not
compensate for a fault elsewhere.
The engine must be at normal operating temperature for accurate idle
speed adjustment.
For information about high altitude carburetor adjustment, see page
