    96 XP revs up WOT on start-up

    Hey everyone I am new here. I picked up a 96 xp for 500$ and have been getting it in good running condition the past few weeks. So far I have Replaced all gaskets on the top end, replaced the exhaust pipe (had a crack at the freeze plug) and just finished rebuilding the carbs. I had to rebuild the carbs because it was bogging down above about 3/4 throttle. Now that I have it all back together I decided to fire it up and give it a test. Now the thing is revving up almost to redline right when i start it. I cant figure out what it is. I have disconnected the carb and throttle cables hoping this would let it just run and it still does it. Does anyone have suggestions?

    Welcome to GH!
    you have an air leak somewhere or your idle is set to high or your throttle cable is out of adjustment
