The 51 still won’t start. We figured out the little gremlins…it was a tiny little insulator between the distributor and housing that someone had used black tape to repair. We had a spare distrbutor and I took the one off that. We went ahead and got new cap, rotor, points and condensor. The coil was ok. When we tried to fire it it wanted to go…..even tried to run….so we think timing is off. We will be back at it tomorrow. Wish us luck
