Good day all!
Dealing here with a frustrating problem on the MX Dart "super bee", first some context:
Car: Dodge Dart super bee (MX) 1978.
Motor: 360 C.I. rebuild to original standard specs (rebuild in 2019). Edelbrock AVS2 carb no more than 2 years. Edelbrock dual plane intake, HEI conversion using 4 pin module, MSD2 coil, new electronic distributor, new spark plugs wires, "fresh" set of champion 12y sparks, everything listed is fairly new and in working conditions.
Problem:
I had a problem with the engine kind of misfire (erratic) when give it light throttle, if you hit the gas the car just pick up an go no issues, it is only on low rpm let's say 1,5-2,0k rpms, past that point the response feels immediate, when I plug the vacuum gauge with all tuning tricks on the avs2 mixture screws adjustments I can get 15 psi but not static little erratic kind of bouncing up and down, but close to 15.
Last but not least I found out that sparks plug came out foulued with carbon (dry), but not all of them only 4 of them in a 1-1 pattern (1 cylinder good and the next 1 faulty) and this happened with the rest of cylinders 1 cylinder good and the very next one faulty. Distributor is brand new (6 months) I already verify gap between reluctor wheel and adjust to 0.008. spark is strong from coil and on to the plugs. Last weekend I disassembled the AVS2 carb just to find a shiny clean interior with no evident obstructions or anything abnormal.
Thank you for reading, any suggestions are welcome. =}
