I just cleaned the carbs and the fuel tank on this four wheeler. When I was done it started and Idled perfect and can run the throttle all the way wide open and has no problems. When you drive it in gear you can only open the throttle a 1/3 of the way and it runs smooth, if you open it all the way it starts skipping and popping like it has a rev limiter on it. Any ideas? Thanks for any and all help on this.
