Newley rebuilt 440 from the get go had popping thru carb on acceleration re jetted carb changed power valve go timing set thought I had it all sorted out went for test ride everything was fine after about 20 minutes started back firing thru carb was barely running limped back to the garage, it felt to me like it wasn't running on all cylinders and I don't mean just one or two it felt like only 3 or 4, I put a timing light on each plug wire and found only 3 cylinders were firing could this be the ignition module
