Anyone have any ideas for what could be causing my problem? I just cleaned (boiled and used carb cleaner and ran small wire through all the holes) the carb again, tried some various main jets and still no better. It starts great and idles great. When the throttle is at 0% and I pop it to 1/4, or even 1/2, it revs pretty well, but when I pop it from 0% to1/2-full..it bogs and will cut off unless I let off the throttle. I can't tell you how annoying this issue is!!! I just want to have fun on it again....it runs, but has no powerband so I just basically putter around on it while my 8 year old son whizzes by me on his TT110..lol.
