check the tbap sensor wire harness. if you do asearch you'll see theres been a rash of them that had to be replaced for some reason. it might be the reason for your missing.

Default Is t-bap sensors only for EFI
My 04 700 sportsman has a carb. Runs fine at idle and no noticable miss until around 3400 to 3900 rpm. After 3900 rpm it seems as if a powerband kicks in and after it starts to slow down it backfires.
