Just bought this 07 predator 2 stroke for my son, needs some tlc, just replace carb, coil and plug. Its peppy when it takes off but after half throttle to full throttle it seems to bog out . It seems to not have and go to it. I also have a 99 E-ton 90cc and it will fly compared to the predator. Any Idea or suggestions estion? Thank you in advance.
