just got my 90 running pretty good, however, it seems like its running a little lean, I know its not all that powerful, Ive installed a new carb kit,plug,adjusted the points (76 atc90) checked the valves. As I was messing with the carb I notice the foam airfilter is gone. I just have the metal cage in the plastic airbox thing. could this be causing it to run lean? thanks Jim
