Anyone have any ideas on how to extend the needle valve stem so I can get it out past the Cowling?



Thanks

Ted shuffled out of his cave and grunted these great (and sometimes not so great) words of knowledge:

There should be a set screw in the side of the needle valve and a hole in the end of the needle valve. Loosen the set screw, bend a piece of

1/16" music wire into an "L" shape, cut to length needed, insert in hole and tighten set screw.

On the off chance you have an "older" engine that does not have the set screw, do the following:

  1. Get a piece of brass/copper tube that will just fit over the outside of the needle valve.

  1. Cut the tube to the length needed.

  2. Remove the needle valve from the engine and remove the O-ring on the needle valve.

  1. THOROUGHLY CLEAN THE KNURLED END OF THE NEEDLE VALVE WITH ACETONE.

  2. Put the piece of tube over the end of the needle valve and CRIMP WITH A PAIR OF PLIERS ONTO THE KNURLED PART.

  1. Apply flux and solder the tube to the end of the needle valve.

  2. When everything has cooled, clean the needle valve, put the O-ring back on the needle valve and crimp the other end flat.
