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).

Removed, disassembled & cleaned carbs. Installed, synced carbs prior to hooking up linkage. Set idle mixture at 2 turns out, then checked sync. Reconnected linkage, then synced at 2500rpm. At that point, had 50 idle jets, 125 m, 190 ac, f7 e-tubes. Running very rich, idle mixture was at 1/4 turn out for best idle. Switched to 45 idles, f11 e-tubes, set mixture at 1 3/4 - 2 turns all around, ran great, idled great, popped at cruise. I've tried different combinations of main, air & e-tubes, but still pops from carbs when at a steady pedal at most rpm ranges and a light backfire from exhaust at deaccel. Seems to pop more with f11 tubes, runs better with f7, 125 or 130 mains, 190 ac. ???
