"Rebuilding" them is quite straight forward. Tuning them id leave to the experts.
I was in your situation, i bought a pair of webers for my xflow, rebult them in a few hours which I found easy with the aid of the instructions in the
rebuilt kits. I was going to have a go at tuning them, but was convinced to take the car to a rolling road.
The guy rr'ing the car changed the pump jets, chokes, emulsion tubes and mains jets to get them running right for my car. I would have never
thought that you needed to change parts to "tune" them!

They're not too complicated, the rebuild kits I bought for my Solex addhe's had exploded carb drawings in, which help.

Each kit was about £25 I think and I needed 1 per carb.
Paid £100 + parts for the RR session which came to about £150.
I left there with 130bhp on my first session. I fitted electronic igniton and on my second session, some weeks later, I ended up with 135bhp.

I found Hammill's book "How to build and power tune Weber and Dellorto"etc invaluable in rebuilding mine. He also offers great
advice on size of jets which makes it easy to get close to a perfect tune.

Which spec carbs are they. Some, the late emission ones, are near enough spot on. Drill the idle jets to 60 or 62 and probably perfect. Worked on my
1800 zetec, same sort of output as the pinto....
