I am working on a 25hp Evinrude E25ELEOA. The motor will idle fine but if I start giving it gas, it starts to flood itself out. I think it may be the primer solenoid. It seems there is a fuel line going from the primer solenoid to the back side of the carb and when I give the motor gas, it starts to flood gas into the back side of the carb and drowns the motor out. How do you test to see if the primer solenoid is bad?? How do they work?? Thanks for the help.

Primer Solenoid
the primer replaced the old choke butterflies in the carborators, pushing in the key activates it, like the old choke plates, but injects fuel directly into the intake.
The red handle is used when your battery is dead, and you have to rope start. You move the handle 180 degrees.
Normal operating position is with the handle back over the body of the solenoid, like in the picture below.

I understand, now my next question is should there be any fuel flowing to the carb from the primer solenoid when the handle is in the closed position.

When the motor is running and I take the line off the top of the carb and rev the motor, gas squirts out of the hose. Should this be like this?? I think this is happening and it is squirting fuel into the intake and flooding the motor out and it is causing the motor to pop and stall.

The primer should definitely not be squirting gas unless you push the primer button or pull the primer knob. I would think with the valve in the proper position it would cut off the fuel anyway. But, you could always take the line off and plug it and see how it runs. Then go from there.
GOod luck,

Thanks for the info. I will go and mess with it tonight and see what I can figure out.
