The Sealey MS013 is a specialised pilot screw adjusting tool designed for precision carburettor tuning, particularly on motorcycles. This 412mm deep access tool features a 90° angled head that provides improved access to hard-to-reach adjustment screws, making it ideal for working in confined engine compartments where standard screwdrivers cannot reach.
