Points/Distributor repair NZ?

[david.skinner]

Thanks so much Brian and everyone else. I'll give you call later today. To fill in the gaps the engine is an 81A and has a crab distributor. I notice that it has about 1mm of axial slop in the rotor. I wonder if this is enough of it to disengage from the cam slot resulting in me seeing no electrical pulses on the coil primary?
