Two cylinders are not sparking or firing.. wires new, points and condenser new, no spark on plugs. Seems to be some slop or play in distributor. Does that mean timing chain or distributor? It will fire up, but no spark on two. Amy ideas? Thanks john

If no spark at those two cylinders it has to be the cap, rotor, wires, or plugs. Nothing else will cause it if no spark.

The timing chain affects all 4 equally, so not that.

Check compression, all 4 should be the same or close.

You have to do a little more diagnosis to determine what the issue really is. Trade the two good plug wires with the two bad ones and see if it changes. If swapping wires makes no change then wires are good.
