I guess I should post this here. I live in NE Wisc and it just snowed a ton and now my quad runs like SH*T!!!. I have a 42 pilot and a 160 main screw 2.5 turns out with the R4 system and no air box lid. The box filled with snow, It ran horrible. Then cleaned it out and put the lid back on and it still ran horrible. I think its the jetting but not sure. It would pop when you let off the throttle and it wouldnt idle. Please help. Oh ya its any wheres 0 to 32 degrees.
