MG Sports Cars

"Not very tunable", seems like (2) proportioning valves, in sync, would do it. roverman.

Please elaborate.

Just theory, at this point, 2 proportioning valves, side by side with minature gilmer pullies, for knobs. Turn the the belt clockwise and both knobs rotate in-sync. Is diagonal better ? Onward, roverman.

Do both valves flow the same?? forget it!!

I know this is an ancient thread, but I'm hoping that someone here has alreday figured out this:
The Wilwood proportioning valves use a 1/8-27 NPT input port. They supply an adapter from the NPT thread to a 3/16 inverted flare line.
MGBs and other British cars usually have 3/16 bubble flare lines, with a 3/8-24 thread. Not metric as far as I know.
I am using a Wilwood valve in my "50s MG Special" (see Project Journals), and cannot for the life of me find an adapter that would be described as:

3/16 (Girling) bubble flare 3/8-24 female to 1/8-27 NPT male.

I sent an email to Wilwood yesterday after hours, so have not heard back from them yet. Their online catalog does not show such a fitting.
I have checked all major local autoparts stores, industrial plumbing shops like the Parker Store, as well as online brake plumbing catalogs, etc.

Any suggestions appreciated.

Suggest you take the easy way - cut off he existing bubble flair and do an inverted flair with your flaring tool and there you go.
