Thanks BB, your enlightening opinion is very valued indeed.
Compression...yep...there is what feels like a fair bit...it blows my hard pressed thumb off the spark plug hole in no uncertain terms.
As for the carby...it just so happens I have just removed it and gave it a bit of a wash. The butterfly shaft you speak of is actually frozen and short of me using a pair of pliers or the like..'she ain't moving"
I have some pics of the carby for anyone to identify and if one the same isn't available or this one is unable to be re-kitted and overhauled...what is the best option ( and why )

of an eBay or Amazon one to replace it?
Can I assume that this is the original carby?...and if so...what was the correct part number so I can obtain a viable replacement?
