I just assumed mine was worn out!

I wonder if the mixture on the MFI screws clicked?
OT:
Jim, have you ever come across part numbers for rebuild kits for Fuel distributers? Someone once told me he had a list, but after pestering the guy for a while, it was never produced. I wonder how they are obtained?
OOT: If you don't already know, I recently came across an area on the BOSCH site "Vehicle Part Finder" that listed their part numbers by application.
