    Questions on '72 Q-Jet

    I have 2 questions about a 7042202 carb I recently purchased. It is a Carter built Q-Jet with a very early build date (G1 - July '71). The carb is for the base 350 w/ auto.
    Questions:
    1) The vacuum break control and bracket, the secondary lockout lever and the fast idle cam are all either painted or plated black. They are not discolored but are a satin black. There is some surface rust on the parts where the paint has worn. Is the black color of these parts normal for a Carter built carb, or am I looking at someone's effort to clean up the carb?
    2) The carb has a plastic choke pull off diaphram case. I have seen '72's with both the metal and the plastic cases. Was this a running change during the model year and if so, approx. when did the change over occur?
    Thanks in advance for your help.

      Mike,

      I've got one with the same date in my collection. Plastic choke pulloff and no black on those parts at all.
