yfz cutting out?

[zyoung04]

my yfz recently had a little problem i lost the idle /air screw so i bought a new one after i got it back together it started cutting out really bad even at an idle and even when you crank it up it never done this before now.....everything is tight so there shouldnt be any air leaks and the only ive changed is i bought a new spark plug thinking that may help cuz the other looked bad and installed a quickshot

anyone know what the deal may be?

did you install spring,washer, and o-ring on fuel screw?

[zyoung04]

yea the screw is still there and everything is still there that came with the screw spring, o-rings etc.....thats the first thing i looked at when i noticed it running weird......i checked the gap on the plug today everything is good there as well
