    I was just thinking that you could also have a vacuum leak if you just replaced the carb boot and it's not sealed somewhere so it may be sucking air. Just make sure it has a good seal

    I ripped the boot when i was trying to get the carb off after trying it and it not running, i was hoping it had a crack in it and that was my problem but i guess not. I know i had a heck of a time getting the carb on the boot when it was mounted to the engine so ill have to double check its actually on there correctly. I tried spraying starting fluid on all the boots and nothing happened, idk if that trick actually works or not

    Yes, you would have noticed something if there was a leak and you'd have to have a gaping hole in order for it to act like it's acting. I still think that something is slowing the fuel flow to that cylinder and it is bogging when you rev it because it is essentially running on 2 cylinders

    So i bought a can of berrymans and took my time to take the carbs apart and clean them and it did the trick it runs like a top now! I dont know if its a problem or not but when the track starts spinning (in the air because theres no snow) it starts jumping a bit. Does that happen when its in the air? Also how tight is the track supposed to be it seems kind of loose but i dont know how to check if its right.

    It should be pretty tight. Go to the first link below and look at pages 9.10 and 9.11. This should walk you through on how to tension it and align it. The second link will get you to the home page. There's a lot of good info here for you whenever you run into your next problem.
