“At end of 1967, John Muller said that we should start our own preparation company. But I had had enough of the late nights.
“Us five mechanics used to be on a split of 10 per cent of the winnings, and with that I bought my brand new Brabham BT21B and, from Cosworth, a lovely 1,500cc SCB engine that Jack had told me about. I won our state championship with that car and engine.

But I started to feel that I was letting the team down and not pulling my weight, and I decided to give it up.
