Sheet, I'd be happy with 40 000 rpm
Yeah, I know what you mean't, it was a typo

Seriously now,
Did you tip the carby upside down or on an angle when you first took it from the manifold?
Reason for asking is that if carby's are tipped over, some of the crap that has laid in the one spot inside the carby for however many years can move or dislodge and can make its way into fuel transfer passages and jets in the carby and block or partly block them up causing all sorts of problems from no idle through to high end fuel delivery problems.
Just one possible cause of many possible causes.
I can't think what to write here so this will do.
