Easy extension for your pilot screw allows you to make adjustments without tools. A piece of 3/16 brass tubing & a 5/64 roll pin (hobby shop or hardware store). Cut a piece of the tubing about 1 1/2 inches long, drill through at one end (90 degrees) for the roll pin handle. The tubing will slide through the hole in the float bowl and just fits around the pilot screw. A dab of JB Weld (or silver solder) and there you have it! I will email you a picture if you want.
