Because it's got a "Stage 3" kit, you know someone has been in there, and chances are something isn't right. Unless the engine is built-to-the-hilt, some minor jetting and mixture adjustments are all that's required - so it may be over-done.

You want to know the Jet sizes, clean everything, and set the float levels. Then you have a place to start.
would a bad gas cap cause it to suck to much air? how do i go about checking the float levels and i beleive i seen a 110 on the main jets. im assuming that thats stock isnt it? i was told it had a stage 3 jet kit but im thinking that it doesnt
