I've got the stock "S" carb. I know, I know... FCR is great and all, but I'll take the improved efficiency being that I put so many miles on it. The problem I'm having: Under medium-hard acceleration I experience slight dead spots in the high end and when cruising at high rev's I experience minor surging. The surging feels almost identical to what you would experience if you were about to run out of gas and had to switch to reserve, but not as severe. I have a stock pipe, 3x3 and a dynajet stage 1 jet kit. Could anybody offer some advice on what to check or adjust? I don't have an expended fuel screw and the brass plug is still in place, so I suppose I'll have to start there.
