Here is a response to the question on this issue passed by a warbird engineer friend to a current early model Spitfire and Hurricane pilot in the UK:
Pilot quote:
Basically, the Spit/ Hurri with the standard float carb (SU) has the cut-out issue with a definite unload. The problem does not occur in normal flight or bumpy conditions but, does happen with low +ve G.
Engineers opinion:
He has not explored the limits of the problem as, you
avoid it by rolling and pulling (no suprise!). The limit is "between
zero and +0.5G".
My Opinion:
So in general there is agreement in these comments and the info written in the AP2095 that has been quoted in this thread. To me this confirms that the current setup is too sensitive.A good solution imo would be < +0.25G for more than 0.5seconds results in the cut.
