Don't know about you, but I always doubt myself before I doubt others! Feeling completely stumped by this problem, I decided to take the refurbished carbs to a professional mechanic to have them checked over. If I'd screwed something up and he found the problem, then apart from feeling a bit embarrassed, I'd at least have sorted the bike out.
Today I got my carbs back from the mechanic and basically, they're spot on!! So God knows what to do to resolve this issue. Think I might just let it all take a bit of a back seat while the sun shines and come back to it when there's bugger-all better to do.
Thanks to everyone for their tips, advice and general comments.
