Festiva Mystery?

I have a 1988 Festiva with carb no fuel injection. I just recently got
it for cheap just because someone did not want it. Ran fine when I
started it up a little weak so I replaced the plugs, distrubuter cap,
and rotor all were worn but no obvious problems. Ran great after that
about 1 day later it started not wanting to take the fuel properly when
you pressed accelerator then right after that it started stalling in
traffic. So I drove it home and it cut off and I got it started one time
ran really rough and the tach was going off and on. Then it cut off and
I have not been able to get it started since. You can see fuel in carb
when you press accelerator and the coil has a good spark, also a good
spark to the plug wires. I am stumped why it won't start. Anybody have
any ideas please email me I sure would appreciate it! Thanks in advance!
