after my buddy was complaining that his sled wouldnt idle down after a run i thought we had left the neddles down from racing in the spring time. so after moving the clips back to the middle position it was still doing the same thing ,[idling at about 4000rpm]. so we took the carbs off to see if we had a cracked reed boot and low and be hold there was a piece of the slide from the carb that had broken off. so we were figuring that this was the cause of an air leak and the high idlebut is this normal on these carbs? ive never seen this happen before . also, the neddles seem to have a little wear on them about 1" from where you put the clips on. any thoughts would be helpful.
