To anyone with Johnson knowledge:
I have a '73 Johnson 115 Powershift. Motor was rebuilt in 12/06 and I rebuilt the carbs hoping to solve a problem.

Since I have owned this motor (6months now) I have had to use Eather to start it when cold. Once it runs, it fires right up every time.

Possible Problems:
1. Gas line Does not hold pressure in bulb. I have changed out all new fule hoses, new fuel pump and filter.
2. Rebuilt Carbs.
3. I can pump the bubl up thill tight, them if I squeeze it once more, it drops all the pressure.

So I have had to use eather prior to launching the boat out, and firing the motor.
It works, but is a hassel.

I adjusted the electirc Choke and linkage to closed position because the butterflies were not closed at all prior.

Any help here would be great. I have possibly thought of Timing? But Do not know enough about these motors yet to warrant messing this up.

Thanks,
