Thanks for the replies all.
I have heard about and had a look into the ZTherapy sets - yours look great Mark - but I wanted to see if anyone in the UK would carry out their 'restoration' services on them like they do with SU's and suchlike.
I've contacted a few companies, I'll see what they come back with. If it's a no then either I'll have to spend the time attempting to do them myself, or consider converting to HS6's.

I looked into this when I wanted to get my Datsun carbs refurbished. I couldn't find anyone in the UK that would do it. You can buy rebuild kits for them but they don't include the Throttle shaft bushes and bearings. If they are worn (and bearing in mind most are over 40 years old) it will suck in air where it shouldn't and you will have wasted your money in buying the kit which is not cheap (around £200) because I can guarantee they wont run right - been there & done it!!.
Z-Therapy replace all of that and as Mark said, they do a really good job and it all looks the Dog's but by the time you pay for postage back & forth to the US plus all the taxes, the costs mount up. That is why I decided to go down the British SU route cos you can get the bits new within days and you can get them built to order or get a used set completely refurbished. It's a heck of a lot cheaper which was a big factor given my lack of funds. The only thing you don't get is a nice shiny new linkage and you will probably have to get the manifold & balance tube polished.

You need to sort that inspection lamp Bud!
You have all that shiny stuff in that lovely engine bay and a grotty lamp. Give it a polish. You never know, at this time of year you may get a Genie appear from it!
