I'm trying to figure out where to go next on my son's Tao Tao 125 ATV. t has a Sputter or miss at the higher RPM range. It start easily and runs great at lower RPMs, but as soon as you go middle to full throttle is starts to skip and spitter. If you slow down, it goes back to running fine. I thought it was likely a gummed up high speed jet, and after seeing that I couldn't take the carburetor apart, I got a brand new one and replaced the whole thing along with a new air filter, fuel filter and spark plug. Nothing changed and it it doing the exact same thing. I'm thinking it is something in the ignition, but I'm not sure what to try or replace next. The parts are pretty cheap, so I'm not afraid to replace stuff, but any help in the right direction would be greatly appreciated. Thanks in advance for any help or advice you can offer.
