Earlier this year, in the summer and fall, this sled ran perfect; it would star first pull every time with two primes. Now that we finally have enough snow to go out, it will not start!
At first I suspected it was the old gas that was from last season which, I admit was kind of stupid of me to not drain it earlier. However, it ran great with that gas a month ago! Anyways I drained it and put around 5 litres of 32:1 mix (is it supposed to be leaner?, 40 or 50:1?). That didn't work. There's fire in both cylinders. I pulled the carb last night and cleaned it. Set the idle to 2.5 and the air to 2.25. That didn't work. I'm lost now.
I noticed after pulling the plugs and doing the whole flooded process, there was a little drop of something black (oil probably) between the electrode and the arm (where it fires). Like literally there was no gap. That is why I suspected I need a leaner mix.
Model is EC340 or something if that helps.

Why are you pre mixing? Does it not have oil injection? Clean or change plugs, look for a good spark, dump a little premix down then plug holes and try. Should fire. If not make sure the carbs getting fuel.

It was oil injected, it was converted to pre mix by one of the previous owners. I cleaned the plugs multiple times and they have good blue spark.
When I clean the plugs, it fires first pull and nothing after that until I clean the plugs again. Is it flooding (stuck needle? The floats are good), or did I mix it with too much oil? I mixed it 32:1

It should run fine on 32:1. Are you holding the throttle wide open? If it's flooded keep the choke off and hold it to the bars, maybe even pinch off the fuel line so it doesn't get additional fuel and also pull it over without the plugs in to clear it out.

After cleaning the carb, the float bowl will need primed, a thimble full of gas down each plug hole for a few times ((as Roudyroy suggested above).
Its a good test to see if it is pumping gas, should start and run for a second or two.

I didn't even know there was a choke on it, just a primer on the right side of the handle bars. I'll try that anyway.
It's pumping gas, I'm pretty sure. But I'll try that as well. Also gonna look at the fuel pump.
