Gents, new to the atv forum. My 1999 polaris sportsman 335 started losing power and stalling out when I would be full throttle or pushing snow. Took the seat off and noticed the air box was broken and the hose was disconnected. The box had oil in it. Replaced the air box, lid, filter breather and spark plug. Now it idles fine and seems ok at 3/4 throttle but then it cuts out. Any ideas?
