Distributor cap, plugs, and wires are brand-new, less than 3 months old.
I have an almost-new coil and igniter that I suppose I could
replace. (My distributor has been replaced, and my old distributor that
"died" has the almost-new coil and igniter in it. I left the coil and
igniter that came in the used, but working, distributor that's in my car
now)

UPDATE: Resoldering the main relay did indeed fix the starting problem,
but the sputtering is still present. I will admit it seems not to be
quite as bad. I suppose I need to get a timing light...

Thanx again to everyone for all your help! :-)

P.S. There were 4 cracked dry joints that I had to resolder.
