I took apart the carbs and cleaned them very well. I replaced the floats(all three), but it still looses power around 2200 rpms. Is there a piece on the top carb that is missing to open the carbs all the way? Because the manual calls it a cluster lever its kinda shaped like the letter U. Can anyone help thanks if you can...... I think it acts like an extention to open the carbs more. Im not talking about the roller...........its something else something lever I'll get back to ya on that one.
