Well, this dang thang doesn't ever really want to start. and it fouls plugs like crazy (every other time you ride it) last winter, sometimes it would start right up, other times it wouldnt start at all, didn't really matter if it was cold or not that I can remember. at least I think it was fouling plugs, from what I can remember, youd switch out the plugs and after 5 or 10 pulls id fire right up. but I went to fire it up today and lo and behold it didn't start even with new plugs.
I changed the needle last winter. it doesn't idle eather, it ran really good for a couple months right after I got it, and when its running it runs perfectly fine and has plenty of power. but if I shut it off or try to let it idle when I'm setting a trap or what not 1/3 of the time it wont start again, but typically if the engine is warm and I give it some gas while I pull it starts, but if the engine cools off at all it wont start.
