Chainsaw Repair

Been running a 500i on the landing in fairly cold weather and no problems . It starts good and runs good .  But I would think if I was up north cutting in the deep snow the filter system would not work at all. It would plug up with snow in 15 seconds .  The 660 stihl setup did not work up there either. Put the old 064 filter setup on those and saws worked good then and stihl made a winter kit for those 064
