Good reply Stainlesscycle.
My reply was in response to the OP and his appearent lack of knowledge so as to give him an easy solution. Too bad he does not say where he is located as I'm sure one or two members here could come over and help out.
I have bought several carbs from Vintage Iron, the last one was for a 1972 CZ400. Like the others before it, it was plug and play. YMMV.
I hope the OP sees this and replies.
