I've read countless posts on adjustments, jets, linkages, etc but I'm new to all of this. Got the car in December 2015, and was told the following: 2.3l, scat c-25 cam. It has the stock non-vacuum distributor w/points, dual weber 40's, ?hex-bar linkage, bursch muffler/no headers. Came w/50 idle jets, 190 ac, 125 mains, f7 e-tubes. I live at elevation 3700'. Have tried f-11 e-tubes, went to 45 idles, ran good at 3500 rpm+, constant pop at lower rpm or flat throttle. Have tried many combos of mains, ac, idles, e-tubes but still pops considerably at flat throttle. Don't have ability to check air-fuel ratio (yet). I'm running out of bourbon-please help (with carbs, have line on more bourbon).

It seems to me that your idle and main jets are too small. I have Dellorto 40's on a 2056 with 34 vents, 60 idle jets, 132 main jets and 180 air. Popping at cruise would seem like it is running lean or has an air leak. Have you pulled a spark plugs to look at the color?
