[big deuce]

Well, I took the plunge and used Eljaro's advice on plugging the holes. Worked like a charm. I also made a tool to redrill the holes. Its made from clothes hanger, yes a clothes hanger. I started to make one in alum, by threading 1/4" rod with the 7mm x 1.0 die. But realized it would be difficult to drill lengthwise without breaking fragile bits, or it wandering off path. So, I got the idea to use a more workable material and the clothes hanger is a few thousandths over 1/4". I covered the end with black magic marker, and threaded it into the port. Then transfered the 3 holes from a good carb with a small needle marking the holes from the inside of the carb body. Clocked the outside, and removed. Drilled the 3 holes with a pin vise in a drill press, reinstall in the plugged carb. Dialed back in, and secured with a jam nut. Proceed to drill the new holes. The pics show the tools. For a one time use, the plastic worked perfect and was easy to machine on a small lathe.
