I have a question regarding a needle valve on a os 61 max. I need to extend it out about 2'' to fit the cowl opening on a super steerman plane. What I have on the engine right now is a 90 bend rod that is too short for this cowl. Need some ideas. Thanks Rick Flyer.
Most OS engines' needle valve bodies have a hole in them with a gib screw to grip a braided wire extension. They also provide the wire and a collet to make the extension from. Need more length? Use a longer piece of braided wire. Where to find the wire? Some pushrod systems are a braided wire in a tube. You can find 'em in most LHSs.
