I have a 2001 johnson 175 carb model j175plsig and when I pump the primer buld it never gets hard. If I pump it 5 or 6 times before I start the engine it runs perfect. Even after fishing a spot for 2-3 hrs it will start with just a touch of the key( at the same time the bulb is not hard). I replaced the bulb, nothing still not hard. I see no fuel leaks in any lines- checked and tightened all connection. I have not replaced the fuel filter yet.

Any help would be appreciated !!!!!!!!!!!!!!
