How is the high speed screw adjusted on a McCulloch chainsaw?

What is the gas to oil mixture for chain saws?
To keep things running smoothly, oil must be added to the gasoline, and the amount of oil called for depends on how much fuel you are premixing, and to the specific gas-to-oil ratio specified in the owner’s manual. The general ratio for most two-stroke chain saw combustion engines is 50:1, though some manufacturers recommend 40:1.

How are the needles on a McCulloch chain saw controlled?
Internal combustion requires fuel to blend with air. The carburetor handles this for Mcculloch chain saws, just as for any small gas-powered yard tools. Needles regulate the amount of fuel and air that are mixed. The needles are controlled by three adjustment screws: an idle, a low-speed and a high-speed screw.
