Just remembered one, though exact details a bit hazy...
zlin 326
priming for start, thought not the usual resistance. anyway engine starts, its warm, so chocks off and as plane parked at wrong end of runway I back track. reach the other end, just as I start mag checks engine stops. hmm, what the heck... few checks later. fuel is off.
had the wind been the usual westerly mag checks would have been done chocks on and then straight down the runway. wonder how far I would have got.....
(something do with having a carburettor combined with an inverted fuel system meant the 326 carried a lot of fuel between the selector valve and the engine so it ran quite some time after cut off)
