With you being in the UK I would guess that might pose a problem getting the rebuild kit. These are quite easy to get here in the US, they can be ordered at a local parts store. What you need is the carb number (usually on an aluminum tag somewhere attached to the carb with a screw). Then try ordering thru summit racing or perhaps JC Whitney or some other US based auto parts supplier. The brand doesnt matter that much they are all quite similar. Hope this helps.
