Doug, You said in your original post that you won the race...congrats! What were the ET's on the passes that were all stable after the 60'? If the ET and MPH increments are close, then a comment earlier about where you are tripping the beams (60') sounds very logical. I never had an issue with wheelies, so I'm a rookie there, but makes sense. We run Eddy 750's on an original intake in "FRUSTRATION". I also have an original set of Carter 750's (not MW). The Eddy's from new were nearly impossible to adjust the idle. Found out the throttle shafts on both carbs were really loose. Had to have them bushed. It ultimately got so bad that the car would idle at 2-2500 after a pass. Good luck.
