OK The others know I ask this question every time one of these won't start and "I just adjusted the points" threads comes up but did you adjust the points with the rubbing block on the tip of one of the lobes the distributor cam or on the flat area? I've run into to many that the guy fighting a no start condition has set the points with the rubbing block on the flat or partially on the flat and the points aren't functioning right.

This is a 6 cylinder Chevy (1951) distributor that is an easy example to look at. You can see where the rubbing block is on the tip of one of the lobes of the distributor cam and that the point gap is right around your .017 to .019.

You also need the connections to the points in the correct spots so that the system isn't grounded out or you don't have current flow through to the points.
