Description
Overview:
The Carb Adjusting Tool - 1 Flat Side is a hand tool for setting mixture and idle screws on small-engine carburettors. It has a sturdy metal shaft with a comfortable, easy-grip handle for steady control during fine adjustments. The "1 flat side" driver profile is designed to engage limiter-style screws commonly found on many two‐stroke carburettors used in garden and light construction equipment. It is suitable for machinery such as chainsaws, brushcutters, hedge trimmers, leaf blowers, and small plate compactors or generators that use similar carburettor designs. By helping you set the low (L), high (H), and idle mixture circuits correctly, the tool supports smooth running, reliable starting, and efficient fuel use on equipment from brands including Stihl and Ryobi.
