How do u fix that ?
if its not fuel injected you can look at the carbs and see two screws the big one for the idle and the small one for the air fuel mix. So find the factory preset for the air fuel mix in the owners manual or online if you don't have it and check if your getting any fuel down the lines.

I would check if your lines have water in them
I haven't seen a model like yours but if you can take the fuel injectors out and see if anything comes out when you crank it. That could tell you if the problem is in the fuel or not

Yea, there’s no plug to do that. I got a siphon but it didn’t work at all. But people are saying too rich or too lean, And idk how to fix that. I’m really new to this stuff.

disconnect the closest fuel line to the fuel injectors and the fuel should flow right out if its lower than the gas tank then crank it a few times to make sure all the fuel is out. then reassemble

I thought that sled used rack style Mikuni carburetors. If so, pull the carbs and clean them, paying particular attention to the pilot jet and pilot jet circuit. It will also have a main jet and a starter jet.

When it dies, do you have spark? What color are the plugs? If the gas is old, replace it. You won't be able to adjust anything with bad gas.

This is what it came with from factory these are known as rack carbs. Those didn't come with fuel injected at all.

Hey! I got it going yesterday, Everything was going really good until today. I am trying to burn all that bad gas out, Put gas down cylinder started then died after I Pulled. Pull cord seems really fast when it wants to start. Plugs were dry when I didn't put gas down cylinder, put gas down in and the plugs were wet.
