Just to note that my Concentric is a 627  - so set up will differ.

just tried recheking where I got the 626 reference .The BSA 1965 service sheets indicate a monobloc 376 was fitted.

found this should it be of use:
http://www.classic-bike-shop.com/carburettor-for-bsa--b40-australian-wd-1967-71-1711-p.asp
but not sure if the set up listed is specifically suitable to the australian bike  rather than Uk B40F model

[Whilst not what was fitted, does the concentric have functional advantages over a monobloc ? Just wondering  whether I get a new concentric should mine prove not sensible to repair  - I note they are cheaper !]

You can check your compression fit by slowly pushing  the kickstart lever.
fI it is hard to turn past compression, its OK.
If it turns over without much effort, then you may need a rebore.

Do you mean with my hand, or with my foot and therefore with my weight on it?
