Bought a 83 diplomat. Someone deleted the lean burn and used a points dist.car runs like it's only hitting on 2 cylinders at idle but seems to smooth out under acceleration. I wired a electronic dist up and still get the same thing.new plugs,wires, cap and rotor,timing set @ 7 btdc. I thought maybe the 2bl carb was bad and installed a 4bl intake and carb and have the same issue. I'm way over it and hopefully someone can school me on this.lol
