i took the carbs apart for cleaning and the plugs were black when i took them out so im going to try running 200 jets as for the float bowls i know the choke side is suposed to have the small brass tube and if you mix the two up when putting it back together it will not start right. These float bowls both have the small brass tube and they are exactly the same so i dont know if this is causing any problems too. I was checking the carbs on another banshee and one read 1-1 and the other said 1-2 but these both say 1-1.
