Now I thought I was pretty short on the subject commodity, for instance, at a club crank-up some five years ago my Mar-Vil started to misfire, stopped and wouldn't restart. I supected that the little spring behind a disc valve in the carb had broken again - it is still sitting in the workshop waiting for the diagnosis to be confirmed! But, during an exchange of emails on another subject, Eric Brain came up with this:-
"I have today started pulling my 1926 caged valves Lister A apart; I restored it as long ago as 1971, took it to early Beaulieu rally - probably even the first Beaulieu. It developed a "clank" when the inlet valve closes - in about 1978! - and I shelved looking at it until I had time."
What's your 'round tuit' record?
