This may sound like a daft question, but a series of explanations has been offered by a 'specialist'
1/ A porous fuel pump diaphragm,( that has now been dismissed as not being viable)
2/ The carb is siphoning fuel into the sump via the inlet manifold ( Again, if that's the case then numerous A7,s would do the same ) ???
3/ My own theory is that as the engine has failed to run/start correctly recently, then excess/unburnt fuel is washing down the bores and filling the sump.
Any other idea to consider ????
