Default Mac cat 839 won't keep running

Bought this second hand with a punctured primer. I've replaced the primer and
fuel pipes and it started ok but dies after a 30-45 seconds. I've stripped and
cleaned the carb and that has made no difference....
is this a problem anyone else has had?

I don't know that particular one, but a blocked air vent in the filler
cap is a favourite. It runs until it's sucked enough fuel out of the
tank to make a vacuum, then it can suck no more.
