I am informed that with a minor amount of fettling Chevvy Big Bore valves can be used in the Sloper. With this in mind I bought a pair last year with the idea of doing so.
As you will have read via various posts over the time I got new ones. So I have a pair of Chevvy valves if anyone is interested. £25 offer??? posted.
