I have a eaton 50cc atv. It ran great, but now it will not excellerate to full speed. It acts like it is not getting enough gas. I replaced the carb with a new one , but have the same problem. Any ideas?

 

is the cable stroking the slide of the carb fully? is your fuel filter plugging off? have you adjusted the turnbuckles on the throttle cable or up there at the thumb throttle to make sure you're getting all of the cable motion available?
