I have a jiffy model 30 ice auger, it will not stay running unless you keep priming it, I cleaned the carb and didn`t find anything wrong with it, put fresh gas in it after draining all the lines, put a new primer ball on it and its still is starving for fuel, I can get to run if I leave the choke all the way on but as soon as I take the choke of it dies out unless you keep priming it
