Have you done a compression test to eliminate the possibility of a valve that
is not closing completely? If you have spark and even compression, it may be
a fuel problem. After you run the engine, take out #1 and #2 plugs and see
if they are fuel soaked.
Keep in mind that a weak spark on those two cylinders may not fire the fuel
mixture. It could still be a spark problem. You said that you touched the
plug wire to the block and got a spark. If the plug is oil soaked and has a
gap that is too wide, it will not spark. I just fixed a FF race car with
this problem at the last autocross. The owner didn't have extra plugs, but a
strong cleaning with a wire brush and setting the gap got him running.
