My pocket bike was in storage for about a year and now it will start sometimes but mostly i have to start it up with starting fluid. When it does turn on it will only stay on for a while. After starting it over and over a couple times it will stay in idle. As soon as I turn the choke off it will turn off after a little while or when I turn the throttle it will just bog and shut off. I have cleaned the carb and replaced the spark plug. Thanks in advance.
