Safety-Needle Adjuster

Needle valves are much too close to propellers for comfort. (When will manufacturers put them at the rear of the engine or make a provision for remote mounting?) You can make this tool by stapling a stout piece of tight-fitting rubber tubing to a dowel rod. To make the “luxury” version, glue a short dowel crosswise to aid twisting. To use the tool, just push the tube over the needle valve, but take great care...
