The crankset/chainring is a Sugino Messenger has been transferred from an old Langster. It has had quite a bit of wear so that might be part of the problem (the sprocket and chain are new).
Alkali - think I probably do need to take a bit of length out of the chain - think the tensioner is sitting at the wrong angle at the moment.
Anyway, I shall look at it again tonight with points above in mind and see how that goes. Thanks chaps, much obliged!
