CIS fuel metering valve r/r

[Ameer Antar]

hey i'm wondering if anyone knows who rebuilds/reman fuel metering valves.
I would think some of the VW places could do it too? But I've never really
seen any mention of CIS rebuilding anywhere. I'm doing an engine rebuild
and I'm concerned about the fuel metering valve. Could I do anything for it
myself? Also, I have a KH-1 metering head, but I might buy a better one if
I can't get it rebuilt. Would a MC metering head be bad or worse for a
12psi KH motor? Thanks for any advice.
