I have a1992 500sl. I rebuilt the fuel distributor. The center valve has a gap adjustment, it’s on the threaded part. Does anyone know how to set that adjustment.

I'm accustomed to directing people from other forums to this place, but for once I'm doing the reverse...Send a PM to a guy named H.D. on Benz world. Or post this on their 129 forum.
