Hi, guys. I have collected a car. The car has stood without any movement for 15 years. So I rebuilt engine and washed fuel system. I started engine and engine started fast and easy and after the starting, the mixture is so rich, that after several seconds of working, I have to throw away spark plugs because of black soot. I turned cold start valve off but it didn't help. So, I have read this website for 2 days with dictionary but I didn't find where on the fuel injection pump there was adjusting screw which adjusted rich of mixture. And also I didn't find how to define whether WRD worked correctky or not. And I also don't hear air rushing and I don't know what to do.
