How to adjust the carburetor on a chainsaw?

The carburetor features three screws: L (low speed), H (high speed), and T (idle). Adjustments should be made with a clean air filter and a warmed engine. For carburetors with limiters, adjustments are restricted to 1/2 turn. For those without, the base setting is generally 1 turn for H and L. To adjust the idle (T), turn the screw clockwise until the chain moves, then counter-clockwise until it stops.
