Vanir - You're referring to "Miss Shillings orifice" (officially Miss Shilling's diaphragm, but I like the pilot's version better) which was a modification on the float carburettor.
AFAIK they were first fitted in '41 and they didnt solve the problem. They let a pilot bunt over, but not maintain inverted flight. Books say it was first used early '41 and was in common use by March, but I dont have the time at the moment to dig up exactly when it was first used. Looks to be after the BoB though.
The starving of fuel could shut down the engine completely if the negative g continued by the way, such as in an outside loop or inverted flight, not just a power loss.
