Phil;
If you are setting points (or trying to!), then you will also want to reset timing, and if you are resetting timing, you will need to loosen the timing clamp on Distributor base to allow it to turn, and if it is allowed to turn, then you can rotate it such that Rubbing block of Points is right on a Lobeshaft high-point (in other words, at max gap)... and that is precisely where you want to set your gap.
...and having made setting the gap simple, you may then proceed with Static Timing as described here:

"...so difficult"...?...not at all IMO!
I suggest you try again, using technique above and you might not need to consider changing to and elec ign...
Good Hunting!
