do these carbs have any known issues? i have on on my ex and i went riding in the snow the other day and now it wont idle. it will run fine on the choke but it will stall without it. it has a 48 pilot and i tried the mixture screw everywhere. could it be jetted wrong for the cold weather? it did idle when i left to go riding. i did hit the rev limiter a couple of times. i checked my valve lash and there in spec. i cleaned the carb twice and it still does it.
