Hey MadMan did you ever figure out how to fix your problem. I recently made a snorkel for my 95 Big Bear 350 and am experiencing the same issues. It idles fine and runs good in high gear, but when you give the throttle quick revs it sounds like its being sufficated and wants to die. I tried to adjust idle screw and fuel mix screw and no luck. Thanks.
