So it sounds like a hot start issue.

Then what is it called if the car has been sitting for ten minutes after it has been running and is hard to start?

Install a fuel cut switch and see if it helps with the starting problem. Because the compression is a bit low (90s), it will suffer floods a lot easier.

Put in some new plugs/wires to help out. Afterwards, just drive it a lot and see if things get better. Some kind of AI or "water treatment" probably wouldn't be bad either.

As I said "Drove the car for a few days everything was fine, now it is incredibly had to start cold."
It is next to impossible to start it when its cold, if you shut if off when its warm is starts up fine as long as you don't let it sit, Even after then minutes of sitting its still easier to start then when it's cold.

Do you think its a flooding issues? I will research a fuel cut switch. oddly enough it acts flooded but if i spray ether in there it will fire right up as long as you don't touch the gas.

(just found that out) so its gotta be a no fuel issue I would assume.
When you use starting fluid are you disengaging the fuel pump?

Had a similar issue. Had to unplug the spark plugs then flush the gas from the plug holes.

So here is the deal. afm unplugged it will run (but real shitty) plug it in it dies instantly, i tried jumping the fuel pump, it started it and it ran let me rev it up and everything. but i had forgot to plug in the afm then when i plugged the afm back in it died instantly. I replaced the afm with one i got off ebay, is it possible that the one i got off eBay is bad? pulled the plugs out both trialing had some unburnt fuel on them.

There is an ohm test procedure provided in the FSM to check the AFM. And used ones can be found on this board in the for sale section.
