I need some help here. Yesterday on the way to work my motor started bogging at WOT. I thought it might be junk in my carb so i cleaned it. Still didnt fix the problem. Im starting to think it might be leaning out since i lost my filter element, because it runs fine with a little choke. Does any one concur with the lean main jet or does any one else have any other suggestions? I cleaned the carb twice and still nothing.
