> I was wondering about the feasibility of replacing the ZS 150
autochoke
carb on my 80 spitfire with a 175 from a TR7 (I don't have the specific
part
nos. handy) and if it would provide any performance improvements. I figure
it probably wouldn't be a straight swap and was wondering what
modifications
I might need to do (needle, swap the autochoke, etc.) Any and all thoughts
on this would be greatly appreciated.

I would worry about the transition from the 1.75 inch diameter carburettor
throat to the 1.5 inch diameter manifold. The turbulence could be
counterproductive. A more common conversion is to get an earlier model
manifold and switch to two 150's (or 125's). But I know nothing about
Spitfires.
