When starting the car from cold on fast idle, the engine is running very rough – i.e chugging with some puffs of bluish coloured smoke emitting from the exhaust. This is accompanied by excessive vibration from the engine. The car pulls as it should and once upto temperature seems to drive as normal without further vibration. I can hear the auto choke probe operating correctly before start up. The engine fires up straight away with the roughness starting within about 20 seconds. Viton O rings were put in about 2 years ago. Smoke stops on reaching normal running temperature as far as I can see from the rear view mirror.
Oil has been in for about 5000 miles, spark plugs were renewed about 2 month ago.
