I worked at Waggott"s in 1963, and I worked with Ken Waggott doing up a twin cam Grey Motor for John Peers Midget speedcar. We ran the motor up on the dyno on a Sunday morning, but had to wait till it was a reasonable hour before we did. For those that had not seen Merv's dyno, it was a very frightening experience. It was all out in the open, in the rear of the workshop, and it had blown the clutch plate once before, leaving holes in the roof. When Ken tried to get it up to full power, he found it was starving for fuel, so he took the needles out of the seats in the carby's [which were 2" SU's ] it was running on Methanol. With the needles out of the carby bowls it run up something impressive, with steam and smoke pouring off the unit and a hell of a noise. I don't know how John Peers did with the motor in his midget, maybe somebody else does?
