has anybody had an issue with their quad running like **** due to the parking break (maybe the cable?) if i have the nut tightened up by the parking break lever, it'll bog down and run like complete ****....but as soon as i start to loosen that cable some, BAM, lol, quits bogging and runs good!! also, i do still have an issue with, while sitting at an idle, if i hammer the throttle it'll bog and wanna die...could that all be related...gas flow is good, carb looks good. no aftermarket mods on this quad at all...
