teazer said:I believe I have a copy of that somewhere here. I had an early copy back in the sixties plus the companion book on porting two strokes. That's what got me started with two stroke. I ported a 225cc Villiers 1H and fitted an aftermarket expansion chamber and made noisy stinky smoke all over Scotland for a while.
The state of the art has changed a little since then, but it's still a great read.
That was decades before personal computers or programmable calculators, so it was all done old school - buy a book and a few files and get filing. No Dremmels or porting tools back then either.
