UPDATE: Got it running and idling on its on WITHOUT choke!!! Woo. I put a 45 Pilot in and a 150 Main. For some reason tho it breaks up when i give it a little bit of gas now? When I say a little I mean right between idle and half throttle.
It got slightly better when I backed out the A/F screw ALL THE WAY OUT...?? Do I need to get a BIGGER Pilot??? The only thing the ATV has is a K&N drop in filter, still uses the stock airbox and stock airbox cover.
Should I maybe check valves tomorrow when it sits and cools?
Idle---Good
Light Throttle, Cruising---- Break Up
WOT---Good
