PERFORMANCE CARBURETOR ARCTIC CAT DVX400 DVX 400 DVX-400 2004 2005 2006 2007 Carb NEW

I bought this carb for a buddy of mines quad. The day it arrived, went to put it on quad, gas was leaking as soon as gas ran thru carb. The screws on carb were so loose, I could turn them with my finger. After tightening up the screws, the leaking stopped, but quad ran like crap. He ended up taking the carb to another mechanic, who said it was way out of adjustment. :(
