I'm surprised to hear that some of the racers are using new Pertronix
dizzys. I think they are made in India; but for whatever reason I'm not
impressed with their build quality as compared with the old Lucas 25D and
45D dizzys. When properly sorted out on a Sun machine 25Ds and 45Ds (Glen
likes the 45D because of its big cap) give excellent service.
A very important issue for racers is cam lobe accuracy which is an easy test
on a Sun machine. I've almost always found Lucas 4 cylinder dizzys to be
right on. Not so much on the Lucas 22D6 (TR6 dizzy) though.
