How are you checking spark? Like instructed earlier? Checking for spark jumping across a spark plug gap in open air is NOT a valid test. It only takes a few thousand volts to jump that small gap in open air, but that low voltage will not jump that same gap in a compressed fuel air mixture. So you have to set up a gap at least 1/4" in open air and see if the spark will jump that much larger gap to be sure the spark is strong enough.
The reason to go on about this is that you have fuel and 'maybe' spark AND if you did not touch the distributor, then the timing should not be off. So it is very probably either bad fuel or bad spark.
Just checking but was the fuel you put down the carb earlier on fresh fuel .... for sure? Any way the spark plug wires were rotated around the distributor cap?
