I`ve had this excellant book on the TS3 since was a young Mechanic and was always facinated by the opposed piston arrangements , and they really did go I only ever managed to drive one but my it was noisey , there was a scare however that the govenor would malfunction and allow it to rev to infinity , a fitter told me if your quick enough and cut the fuel lines it could be saved from blowing , maybe he was trying to scare me a little.
