Assuming the bike was running on all 4 cylinders before, the points you didn't change should be working fine. You should be able to get it close with the static adjustments.  When the points rub block is on the highest point of the timing cam, that should be the gap specified in the manual.  On my son's CB550, I think it was .022" or somesuch.  If there's still no spark in there, either the points may be grounded somewhere (the little bolt that holds the wires for the points and the condensor), or there's a problem with the wiring or the coils.

I'd suggest pulling one of the spark plugs from the head, and placing it on the outside of the head somewhere.  Turn over the engine and see if either pair (1 and 4, 2 and 3) delivers a spark.

You checked the IGN fuse?

Just a few things to check.  Good luck, and keep us informed.
