i bought a used 2001 warrior. the idle was high after it warmed up so i turned down the throttle screw. while doing this a burst of gas-air came out of screw. now when it idles it dies as this burst of air-gas is spitting out of throttle screw. when i turn throttle back up it runs pretty good, only doing this burst of air very rarely, but then the idle is way too high.
anyone with any idea why?

 

sounds weird never seen it before does it stall when it happens

 

only when idling or when i let off the gas, whenever i give it gas it rus just fine

 

pull off linkage cover and inspect moving parts
