Are you sure it's not just having the choke on and the engine's getting so
much fuel as to choke it?

Take a look at you timing.

I think this might be timing. I'm not sure.

Um, what's overrun?

Once again, check you timing. Oh! and this just came to mind- when was the
last time you replaced your fuel filter? A clogged one will cause many of
the problems you describe.

That makes two of us....;-)
so am seeking some advice. Aside from the

I don't know what to say about that....
could it be a timing

marginal coil? marginal plug leads?

All possibilties. Don't you love British cars? ;-)
Hope this helps.
