    197 kawasaki stx 1100 carb help

    i have a 97 stx 1100 it boggs down when full throttle if you let off the throttle for a split second and gun it again it takes right off.. the carbs were rebuilt because the last owner let gas sit in the tank and carbs for a few years.. so i sucked the old fuel out of the tank and checked compresion it 110 in each cyl and put new plugs, fuel lines, and new filter.. what can i try next please help????

    given that it sat with stale fuel

    +1 on the non invasive seafoam procedure.

    The pick-up screen in the tank could be gummed up if was old gas and they didn't put stabilizer in and have partial blockage. I have heard of sea-foam but never used it. Not sure if that stuff will help clean that or not. Something to keep in mind though.

    Also on the carb on the jet plate below where the needle and seat is. Their are some screens and a lot of people don't replace them when they are rebuilt. They can get real yucked up too.
