Hey Shaggy, what do you mean "butchered"? Having flown and maintained both I don't remember anything particularly brilliant about the Gipsy Major. All I remember is having to put oil in it all the time, the mess down the underside, spares difficult to get hold of and very expensive, inferior power to weight ratio over the Lyc 360 and I am told the RAF always operated it with the Carb Heat wired in hot all the time - why was that then? I know which I'd sooner have!
