Tomtit starting method

Most interested to see the comments re starting the Tomtit with the magneto. Father did ask Shuttleworth about trying his method but they were not interested. Are they more open minded or adventerous today I wonder? Or maybe there is a good reason why they don’t start it this way. We used to have to swing the metal props on the Cessna 150’s most of the time at the flying school where I got my PPL. We were shown the correct way but there is always an element of risk in any task like this one. John Shipman
