Distributor spindle tolerances; original and accuspark comparison

[JonE]

For distributors with points movement in the spindle is bad news as it affects the trigger point and the dwell.
However with the magnet sensor I doubt if it makes any difference to the performance.

That's why I was a bit wary of posting... but I'd be interested in others' views with new units. 
It is difficult to quantify the movement, but it's enough to give a v. slight 'waggle' when grasping the bit that the rotor arm attaches to, inside the distributor, yes... or grasping the cog at the bottom of the unit and moving it sideways with the distributor in your hand.
