How to extend the needle valve

Try cutting the existing needle valve shaft and then using short pieces of brass tubing to splice in a length of cable type push rod. Solder the splices in place. This would retain the original knob yet be flexible.

Does the Pro .25 have a hole in the end of the needle, and a set screw on the side? If so, use a piece of music wire.

Sorry, I got distracted and forgot to give you the rest of the answer. If you don't have a hole in the end of your needle valve, solder a piece of wire to the end of the needle. That's the way it was done in the olden days. Put an L-bend in each end, one for your fingers to grip and the other for added soldering area.

Take the needle to a machinist and ask him to drill a hole in the end, tapped to match a pushrod end. Make an L-shaped handle out of a pushrod end, thread a nut onto it, screw it into the needle, put sme Loctite on it, and tighten the nut down to lock it in place.

Slip a piece of fuel tubing over the reeded end of the valve. The length is determined by your distance from the engine to the outside of the cowl.

A piece of stiff plastic tube, like for fish pumps might do the trick.

Im guessing this needle valve doesnt have a hole in the center and a set screw? I just take the proper length and dia of pushrod, bend the end that will stick out of the cowl to an "L" and go from there. The trickiest setup was where I had to rotate the needle valve around to where I could reach in thru the front of the cowl to get to the socket head setscrew.

Yet another method: Using a Dremel tool or similar, slot the end, then glue a guide tube into the cowl to line up with the end of the needle. Then an ordinary small screwdriver can be used.

There - lots of options! :-)
