Thanks for the replys. I have rebuild kits on the way, Royze major kits. I also have the manuals for the carbs. The chokes seem fine, close when cold, open completely in about 15 minutes, front before the rear. It will idle and run smooth when on the cold circuit? but once the chokes are fully open wants to stumble and stall. pumps etc seem fine strong squirt both front and rear. All of the emmissions stuff is present and seems to work. (vacuum switches, temp sensors etc) The last zenith/solex carbs I played with were on Opel GT's years ago. Replace with a DGV Weber. I may do that here as well but do not want to spend $1K right now. Tristar, I will try and send a picture, Basically what is missing is the spring, nut, and the adjustable bolt and lock nut that threads into the shaft of the vacuum module. The module itsself is there, but the parst that set the adjustment are gone.
