Why fit these adjusting screws?

The benefits:

• Adjust the carburation trackside in seconds.
• Adapt the setting to the day’s altitude and temperature.
• Anodised aluminium knob, easy to see and turn.

When should you replace this part?

A mixture that is too lean makes the engine run hot and can seize it.
