MFI Stacks - converting a T Stack to 'S' specs

Hi,

Need some advice / recommendations as to who can bore out a set of plastic 'T' stacks that I have spare. I'd like to get them to 'S' specs. I'm doing this as I would like to get rid of the cold start spray (1970 design that sprays down into the trumpet), to the later design where the cold start fuel feeds further down the manifold.

Many thanks

I had a couple of sets of 2.4E plastic stacks bored out to S/RS specs several years ago - but by Henry Schmidt at Supertec in the US.

In the UK the first suggestion that springs to mind is Neil Bainbridge ...

Or maybe Greatworth classics, they have a nice machine shop with a good milling machine. Restore Webers too I think?
