I'm told, by a bloke who works at my nearest branch of Halfords, that their original and revolutionary ratchet-free, silent check versions are still available, but not at £20 or anything like it.
That said, I've now used the 7/16" one from the noisy and
comparatively cumbersome set I received and have to admit to being more than slightly impressed by the way in which it managed to make short work of the much overdue task of getting right in about at the nuts that hold my carbs against the manifold.
Anyone who knows the Stromberg-equipped Dolomites will know how awkward their carbs can be to remove, manifold on
or off. But that spanner fitted right in there and it only took me ten minutes to replace both rubber gaskets, previously a slow job with the open end of a combi key, in and out, a couple of degrees at a time until the carbs were far enough clear to enter the ring end, then the inevitable backing off to centre the olives and get the - invariably trapped - ring out
to finish with the open end.
Thanks Halfords, I'm missing the whistle already!
Ive got a sykes p set and they were purchased indivigualy with 11/16ths
