When the engine is cold, it starts ok but at idle it is irregular, shakes and seems to backfire. It turns at between 900 & 100 RPM. After 5 or 6 minutes, when it's warm, it stabilizes and works fine the rest of the time. Changed spark plugs because they were sooty and black. Changed fissured distributor cap and spark plug cables. Smoke at tailpipe is white. Still searching for the cause.
