Hi,
I bought used set of carbs for my 1992 ST1100AN (European model) which is re-engined with year 2001 engine. DHL brought me those carbs but there's differences. They are about 2000 something and from some European model but they have different idle mixture screws, my earlier carbs had cross-shaped ends but these screws looks more like a half moon AND the carbs have some kind of extra low-pressure system, pictured below. What on earth is that?
