James, your problem is almost certainly a sticking needle valve in
each float chamber lid. This comes about over time on all delrin
valves and is caused by varnis build-up in the fuel. Its a simple
procedure to rectify. Remove each valve and carefully but thoroughly
abrade it with some fine glasspaper - especially along the fins and
fin corners at either end. Then roll some new paper into a tube shape
and ride it up and down the valve housing in each lid. I was given
this solution by an AA man forty years ago on my Sprite and I've used
it ever since. Did the same to the SU's on my 2000 only a fortnight
ago and everything now running perfick.
