I just bought a 1995 40Hp Evinrude motor. Recently I took it out on the water and was unable to keep it running for longer than a minute. I just had the oil resevoir taken off of the motor since I didn't have room for it in my boat. Now I mix the oil 50 to 1 ration. I noticed that the bulb was going limp as it died. If I keep squeezing the bulb, it's fine. Could there be a sensor that is stopping the gas from flowing through? I'm trying a new gasline and bulb tonight. If that doesn't work, then what are some suggestions. Any help would be appreciated.
