2001 all stock. Son was riding and reed broke, put new reeds in and now wont run right. it will idle great, has great throllte response, but put the thing into gear and take off it will only bearly hit the power band and acts like its runnin out of fuel. so in the process of rebuilding the carb, installing new reeds, making sure the thors was unhooked, I rode and shut the fuel off, just before it runs out of fuel it runs great. The floats are set at 21mm. I just dont know what else to look for.
