its one of my customers mowers and its probobly not been used in a year so far ive drained the old gas and filled with fresh ive also taken the carb apart and cleaned it but it was already clean it starts right up on the first pull it has a blade clutch that you have to engage "lightly" so the engine doesnt die this could also be part of the problem but once you get it engaged and start mowing its fine for about 20 sec then it sputters and dies and also backfires enough to blow the airfilter and cover about 2 feet from the mower ive also tryed lossening the gas cap incase it was clogged but it didnt help any suggestions would be good ive never come across this problem where i cant fix it
