Success! I drilled a small hole in the broken needle about 3/8" deep.
Then found a hexed Allen wrench slightly bigger than the hole and
tapped it down. Heated up the carb body with a propane torch
for a while and the needle unscrewed !
Having no new needle, I decided to fix the old one. Found some
small brass round stock, drilled the same size hole in it as the broken
part, did a little machining to make a shoulder for the spring to ride on,
then cut off the Allen wrench the correct length, put a little epoxy
in the holes, and joined the two halves together. Seems to work good!
