my 1982 atc 250 r keeps flooding i have tooken the carb apart many times and reset the floats ive changed the spark plug many times and it sparks great. Ive changed it to hotter heat range plugs but it just floods out or backfires it wont even run anymore it used to run great and it still has monstrous compression.

Take the float out of the carb and submerge it in a can of gasoline and see if you see air bubbles. Or shake it in your hand and see if fuel is in it. If it's got a hole in it it will flood everytime.
Also make sure the choke is not getting stuck in the closed position. The choke cable may be broken or the choke is stuck. That will cause flooding too.
And yes your gonna have to change the spark plug again.
If you find the hole... Get the gas out of the float and use either JB weld to seal the hole or use a product they sell in the automotive section of Walmart and purchase a tube of Seal All. Once this stuff dries it won't be affected by gasoline or oil and should be permanant.
Then put everything back together. Turn in your mixture screws on the carb all the way in. Then turn them out 1 1/2 turns and try to start it. If it starts your gonna have to fiddle with the screws to get the mixture right again. Counterclock wise will give more fuel or richen the mixture. And Clock wise will give less fuel and lean out the mixture.
A Hole in a float can be frustrating because it's not always obvious.

You do have a carb problem and not an ignition problem. You said you reset the floats? I'm assuming this just started giving you trouble?
Make sure you followed the exact specs for the carb, bike and motor series. The specs can vary a lot, and since I don't know what your elevation is, you'll have to check for that as well. Mountain riding requires different settings then at sea level.
Make sure you blow compressed air thru all the jets, nozzels and any nook and crannies you can see. Clean means perfectly clean.
Check the float level needle very carefully with a magnifying glass, if the tip is dull, bent or nicked you'll need to replace it. A new needle will come with a new seat.
Make sure, when reassembling the carb, you do not force anything Make sure the float is not binding, everything has to fit nice and easy.
Make sure the air cleaner is not clogged, and make sure the throttle cables work nice and smooth.

Most likely is you have a bad needle and seat in the carb which allows fuel to enter even after the float seems to close the flow. Take the float bowl off and remove the inlet needle, you will probably see a ring around where it seats which is the culprit. I wouldn't go kicking it over with the spark plug in it, that compression you feel may be the bottom end of the engine filled with fuel and could bend the rod. Replace your reeds while you're at it.

like every other running toy from the 80's the plastics were crap and "Bakalite" was king Its 98% the reeds which were the newest plastics that rotted away(crumbled) the carb peeing is stuck floats, so replace the reeds, clean the carb, use synthetic pre-mixing oil This is all based on the assumption that 'draining' means fouling of the plug

The problem isthe float needs to be adjusted so the fuel shuts off sooner.
You can do this by removing the sediment bowl and bending the float arms slightly but be sure to only do it a little bit at a time to insure proper adjustment.

The CDI may be going out,also change the coil with a known good one to make sure it is not breaking down.I had this happen on a 86 Kawasaki three wheeler.
and it was the CDI.

carb seats and neddles would be my guess. They will where out over time and let fuel through causing the engine to flood.
Good luck

check the timing marks under the side cover first. then check needles and make sure pilot jets not plugged.
