It's a fairly simple matter to set the idle and low-speed screws, but setting the high-speed screw is challenging and shouldn't be attempted without a tachometer.

If the carburetor is so far out of adjustment that the engine won't start, turn both the high-speed screw -- H -- and low-speed screw -- L -- clockwise as far as they will go, using a flat-head screwdriver, then turn them counterclockwise by 1 1/2 turns.

Turn the idle screw -- I -- clockwise until the chain starts to spin, then turn it counterclockwise slightly. Adjust the screw to find the highest setting possible without making the chain spin. Check the setting by holding a digital tachometer over the spark plug. It should read between 2,700 and 2,900 rpm.

This adjustment may throw off the idle adjustment, and so resetting it may be necessary.

It should be fewer than 13,000 rpm.
