Blackdog_kt you have probably right. Most opinions and data claim that float curraburator under negative G casue engine stall due to fuel lost but probably the truth is that lost power is beacuse of fuel flood curraburator and engine. When you apply negative G float in curraburator is going up and fuel flood curraburator. Probably with prolonged fuel flood engine could stop and then could be little problem with start it again. Of course moving prop will start engine again but it could need some time to do it.

I have a few time problem to start on ground inline engine of plane beacuse i gave it too much mixture.

I think Ms Shilling Oriffice was a small disc with hole to prevent fuel flood curraburator.


Ad to video with Spitfire flying aerobatic when he is making inverting flying he is actually in shallow dive with throttle back.


JG4_Helofly Spits or Hurricanes from BOB era have not too much engine workload. You opearated mostly throttle level beacuse you got CSP ( constant speed propeller unit) which mean that you just set only wanted RPM ( in fight maximum possible, in cruise depend of economy of fuel) and mixture level was also only for economical flying ( auto - reach - lean). Much more work load have planes with variable prop pitch like early 109s and early russian planes.
