I had bad gas in my generator, so emptied the fuel tank, flushed line from there through carburetor bowl. There is fuel flow through bowl via the drain. I did remove the carb and cleaned the float and needle, and also cleared the tube, dont know what its called, from the bowl to the carb. Can’t keep it running. If I spray the carb it will run, but otherwise no. Generator probably doesnt have more than 25 hours, but is 4 years old or so…ideas ?
