Was riding on the trails recently first couple hours went good after it got a little warmer in the day maybe 40f. The snowmobile had no power kept bogging,backfiring when I gave it gas wouldn’t idle had to be towed back. Wondering what you guys think it could be.
For reference I had cleaned the carbs on the sled put new fuel lines from fuel pump to the carbs as they were kinda suspect also put in 3 fresh spark plugs and gapped them accordingly. Any help would be greatly appreciated.

Start with a compression test.
did you try it with carb heaters turned off?

The guy I bought the sled from disconnected the heaters. I just haven’t got them hooked back up do you think I should hook the heaters back up?

I will do that thank you.
no. them being on can cause issues like described whne it is warm out. just make sure the fittings are capped in case of a leak.
