Finally picked up a McCulloch at a really good price, the bay hunt is over.

Putting a few bits together in a box to bring back to the UK, does anyone have any ideas what to use carb/throttle body wise? Be quite nice to run some EFI set up but I can only find parts for 1000BHP cars. In a dream world it would be great to run something I can see whats happening on a screen. Any advice is much approached as ever you clever chaps
