Fulvia - misfire when hot / traffic jam

[Keithver]

sounds like a possibility. When I assembled the car. I had nothing on cylinder 1 on idle. I took the carbs to a specialist to have everything properly internally cleaned. THat did the trick. Firing on all cylinders now - happiness

What distributer are you using? The original or an electronic one like a 123. If electronic suggest you use a new digital voltage regulator as electronic ignition is VERY voltage sensitive. Too high a voltage causes it to momentarily cut out. I had this problem and it took me an age to trace. With new VR the problem is solved.

The carbs may need balancing with a vacuum gauge. Slightly undo the idle screw for cylinder #2 to increase fuel delivery.
