vacuum line are right ,I'll check line again today. thanks so far guys
You are going to have to eliminate things one at a time. If you are positive its not your carbs which I beleieve we are going to find out it is. Other things to check to eleiminate them is your fuel screen / filters inside the tank and your fuel pump. Another thing to check is if the floats are sticking and pouring too much fuel in one or two cylinders. Check your plugs after you run it for awhile.

What about the little O rings on the top of the carbs under the covers? I dont know what they do when they are missing but everyone says if you forget to put them back in the sled will run like crap.

first time the problem it started I didn't even have the carbs apart to lose or mess anything up,just took them off to see if the first owner set the mixture screws to 2 turns they were so I put them back on synced the carbs and now this,drained flushed tank,checked filters ,cleaned carbs and soaked jets 3 times ,tried my last plugs that were good when I took them out but ordered new ones to try just in case. just got to keep trying things you guys are a great help i'll keep you posted

You say it helps if you richen the idle jets by a 14 turn. Have you tried running with the choke partly on at 1/4 to half throttle where your bog is? If that cures it then you know its fuel related.
Is it a steady bog at those throttle settings? or can you slowly squeeze the throttle and it passes through that range with no bog?
You say you soaked the jets! Did you run anything through them? Can you see through them? A bog in the middle and it runs fine top and bottom tends to rule out plugged filters cause it would be worse on top. It rules out plugged idle jets. It knda rules out spark because spark would be worse on top.
Are all the passages clear in the carbs? Taking off the carbs and playing with them could have moved dirt around. It is possible that any of the carb passages are plugged! You did blow out all the passages and jets right?

tried the choke but was hard to tell I thought it helped a little once ,did the jet with a wire and soaked overnight,blow carbs out with air and cleaner,we have no trail system so just slow woods trails and fields works fine in short trails but when you come to a field give it any then say a 1/3 throttle goes great till it gets up to a steady speed then just feels dead ,you can ease the throttle more and more till at least 3/4 before it takes it again , and the fast you go and slack back a little on the throttle the worst it is.
Sure sounds like its carb related to me.
