My motor seems to die while its running at any speed and the primer bulb keeps going soft in fact its hard to even get it firm . I was wondering if it was the bulb or the fuel pump . It will stay running if i keep priming it but a few moments after I stop it dies . This happened on my 50hp a few years ago and it turned out to be the pump. I also noticed that the brass fitting on the tank was lose and tightening it didn't help. I rebuilt the carb last spring but I'm going take it apart again just to see if the float is working .
