Hey guys, I have a 5 year old 21" Craftsman push mower with a 5.5hp B&S motor on it. It is one of these no manual choke no adjustment carb motors. I am having a problem with it dying on me. If the motor is cold, it will start right up and run fine for about 5-10 mins and then it just dies. Then it is very difficult to start and I have to wait a few mins until it will turn over again. It will run for a couple more mins then die again. It will continue to do this and is basically un-useable. I have taken the fuel tank off and cleaned it out, taken the bowl off the carb and cleaned it out and the inlet and made sure the float was still working, put a new gas cap and fuel line on and the spark plug, oil, and air filter are all clean. I am at a loss here. Looks like some kind of governer/choke arm off the carb that I am suspecting could be loose or something because the mower will idle fine if left alone in the driveway but will continue to die when being used to cut grass. Can anyone offer their opinion on how to get this thing running right again, they don't make them like they used to! This thing should be just getting broken in by 5 years! thanks for all the help
