23. CARBURETOR TUNING
23
This section covers carburetor tuning. Included in this section are basic settings,
idle speed adjustment, and complete adjustment.
The carburetor has been set at the factory for optimal performance and compliance
to EPA Phase I emissions standards. However, minor adjustments may be required in
certain conditions, such as high elevation.
NOTES:
• These cut-off saws are equipped with an electronic speed limiter, as part of
the ignition system. This will prevent the saw from going above 12,500 rpm.
Attempting to set the carburetor mixture to increase the speed or power beyond
this limit may seriously damage the engine.
• Always check the air filter, pre filter, fuel filter, and spark plug before making
carburetor tunings and clean or replace if necessary
