Not sure whether I'm stating the bloomin obvious here, but you've tried the spares list, right?

Make one out of alloy on a lathe. Can even be solid if you like. I'd turn one up for you but don't have a spare timing cover anymore for exact dimensions.

Hi Douglas, If i get you the dimensions or send you an old one - can you please make a couple? Cheers Peter

I'd rather have a cover with me, when talking about thousandths for an exact fit. You should move to Victoria for me to help you, it's too hot and muggy up there! It will probably be a standard 1/2 inch welch plug. Google welch plug suppliers.

Is it a fancy brass one?

what the hell is a 'welch' plug, is it some scary thing from the colonies? most kind regards.
