Well I modified my distributor today and put the 64 jets back in and returned it to my base settings. I regained control of my idle and it performs extremely well again with the exception that the surge it back/still there. I ordered a set of 66s today that I will install tomorrow, it will be too rich I believe but I can at least see if it solves the surge and go from there.

I also took some pictures of the metering block and the bowl so maybe someone can tell me if they are 340 or 440 pieces.
