Ok, Gary, did you get a good ashtray?!
I’m glad you finally got your baby! She looks good from your pictures.
Clutch adjustment is very simple. The end of the cable has two nuts. Loosen the last one, get the clutch adjusted, and then tighten the two nuts together so they don’t loosen.
I agree with Lou, unless you have reason to believe they’re ok, the boosters are suspect. Very suspect if they are the original Girling units and haven’t been rebuilt. A bit less suspect if they are rebuilt original Girling units, and could very well be good if they were replaced with Lockheed units. It’s common to delete them and replace the master cylinder with a smaller one. Just to be counted, I have a standard replacement M/C with Lockheed boosters and I’m very happy with my brakes. When bleeding brakes, remember to start at the wheel furthest from the M/C. On a US Europa, that is the passenger front wheel.
The Gunson pressure bleeder looks like a good unit and one of the things that makes it good is that from the pictures I’ve seen, it looks like they have the proper cap for the standard brake reservoir. I have a Motive Products pressure bleeder. They offer a huge selection of adapters to fit most M/Cs but it wasn’t huge enough from my M/C. I didn’t think there was anything at all unique about the original reservoir cap! I happened to have a M/C reservoir cap from the original M/C and I was able to make an adapter with it.
I have nothing to add about the tranny linkage.
