i hav a king quad 300 that was running fine. now when i start it, it takes longer to fire up then it runs ok for a few mins then when it warms it misses and backfires. it may choke out itself. it seems to want to run beter at low revs. the choke cable has broken but has bin broke for a wile and wos running ok with it broken before. any help would be great as we are expecting snow here and could do with the quad sorted. thanks. robbie
