If you keep guessing or start replacing things, you'll go nuts trying to figure this out.

You originally said "new spark plugs are firing", but then you immediately said "it seems to me we are not getting spark". Check for spark and report back.

You said ammeter is not deflecting when you turn on the key. That's OK, depending on whether the points are open or closed. Each time they close as the engine rotates, you should see the ammeter discharge slightly.

You say that the plugs are never wet. I would think by now that they would be saturated if you are getting gas. Do a compression check to confirm that the valves aren't stuck open.
