I am doing a minor tune up on a 59 TR3a; plugs, points, condenser, etc. I am using the static timing procedure described on the Macy's Garage website. The car ran reasonably well before I started, but now it won't start. I noticed that with the distributer cap off if I try twisting the rotor, there is a considerable amount of wiggle in it. The rotor is not loose on the four sided cam, but the whole cam wiggles with the rotor. Is this normal or should it be tight?
