RE: Cox cylinder/head tap
Sounds good if it isn't too much hassle. I have to ship across a border, but it may be worthwhile if I make a few sets. I am not sure what thread the KK needle was. Mine was .083" OD which is kind of bigger than a #2. Maybe I should check the one place here, they were successful for the Turbo plug tap size. I have been using a 2-56 for some needle valves, but a finer one would be better.
