Has spark, won't start even with starting fluid

I have 95' Trailboss 250. I can't for the life of me get it started. I have a new spark plug with good spark. I've tried starting fluid and can't even get a pop. Even if I'm not getting gas, it should pop with the fluid...

Any ideas? I have to be missing something basic, but what?

Start here....

Check the battery
Check the spark plug
Change out old gas and drain your line
Check your oil and lines
Check and clean the carb, jets, valves and float bowl

Do you hear anything at all? Are you even getting the starter to turn over?

polaris 250

To run, it must have 3 simple ingredients:

1) Spark,
2) fuel, and
3) compression.

You said you have spark.
You said you added fuel (starting fluid)

So, you need to check your compression. It might be time for an overhaul.

Check your electrical, even with low compression you should get something when you try to start,maybe you have a short somewhere

My Xplorer 400 had the same issue when I bought it. Ended up being a bad pick-up coil. A chunk of crap from the recoil (elect. starter was bad too) had came loose and smacked the coil cracking the plastic covering and bending the mount. Replaced that and it fired right up.
