Just finished putting the head back (valve job) on a friends MGB and when we went to start the car there was no spark at the plugs. The pertronix test as dead, the coil kept changing the resistance across the terminals. Coil is probably original. Anyway, replaced both, which require new timing since the new pertronix put the unit in a different spot on the plate versus the old unit. Got it started and it revs fine sitting in the garage. But driving it, there is a miss about 3000 rpm and perhaps some knocking. So I assume the timing is still off. Would you guess that it is acting like :
too much advance?
too retarded?
Anything else to check?
