I have a toa toa 110 cc atv that i purchased a new carb, starter and battery for. I got it started and it idles perfectly. I then adjusted the carb. When I go to accelerate the atv it gives me a hard jerk every other second or so. The hard jerk is the most noticeable between idle and wot. After i get to high rpm its not as noticeable. I dont think its a lean pop because you cant hear anything from the exaust that sounds like its running lean. As soon as I start givng it gas after idle it seems to `miss' until high rpm. I can get it to wot and top rpm easily while riding it. The miss ,if thats what it is, is persistent the whole way though. I`m not sure if this is a valve timing, carb, or ignition issue. I dont think its slipping in and out gear. Any ideas on what the problem is would be much appreciated.
