Sled won't start after flooding, read description?

Question

It's a 1976 ski-doo everest (340 rotax). I rode it 4 days ago & it ran fine. 3 days ago I accidentally flooded it by priming it too many times. I pulled the plugs and fuel pump line (the one that connects to the engine, not the carb) & pulled the engine over it to clear out the excess gas. It sat for 2 days, but now it won't start no matter what (it used to always start after 1 or 2 pulls). I tried new plugs as well the old ones (which weren't great). It has excellent compression & lots of spark. Stuck on this one, so any help/advice would be great. Thanks

After the fuel dried out of it from the flood, it's got alot of oil film. I bet when it fires up, it will smoke like hell. Shoot a shot of Starter fluid in it while you crank, but don't drown it. At least something to make it cough/show signs of life.

In the future, I would use a different gas. If the boiling point(distillation curve) of the fuel is too high, it will be hard starting because distillation curves drastically effect a fuels ability to vaporize. Don't over Octane it, either because Octane is anti-ignition. Depending on how much fuel quantity you bun through, I can suggest a specialty fuel for you. At 5 Gallons at a time, it's not a hard pill to swallow, if you don't ride often. This fuel will COMPLETELY get rid of the groggy cold engine manners.

Air in the fuel lines, is the carb filled with fuel?
