There was a discussion a couple of years ago about the size of the loop and number of turns for the loop. I've had several NOS priming wires over the years, and have misplaced or sold them. I recently acquired another and here is the information. Outside diameter of the loop has an O.D. of exactly one inch, and the number of turns for the wire in back of the loop is exactly two turns. The length of the wire varies due to the brand of the carburetor, but the loop ends right at the radiator.

Larry, is it brass wire, or copper-washed steel like welding Rod for oxy-acetylene used to be ?

It is a raven finished steel wire. I use the welding wire for my brass T's. It's just nice to have an original around. There are so many T's out there with weird looking priming wires. Some guys don't even bother to find out where they put the hole in the radiator trim, which is terrible.
