1994 30hp part ID

[Sonwatcher]

I just purchased a boat with a 1995 30hp Johnson motor . As I said I just bought it so no manual yet. Could someone tell me what a certain part is and what it does ? If you are facing the front of the motor it is on the left beside the motor . It has a red dial directly on the back end that turns like it is opening or closing something. The part itself has 2 small rubber hoses coming off it that go to the top of the carburetor. I noticed the red dial in the back is turned fully counterclockwise . Is that where it should be ? Any info would be greatly appreciated.
Thanks !

Primer Solenoid
the primer replaced the old choke butterflies in the carborators, pushing in the key activates it, like the old choke plates. the hose injects fuel directly into the intake manifold.
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.

corrected this is right picture

Thanks for replying. But the pic above doesn't look like the part. The part I am describing is a mostly flat black plastic with 2 lines going to the very top of the carburetor connecting to nipples on a plastic piece. There is a red plastic pointer dial off the very rear of the back that turns up and down that is all the way turned counterclockwise .

Ok, rather than trying to go by memory I got a pic of it. 1 hose goes to the fuel pump the other to the top of the carb. It is round on the bottom and flat on top.

I found a description that identifies it as you say and how it operates. Thank you very much !

Re: 1995 30hp part ID

Ok, I just checked the model# of the motor. It seems it is a 94. The # is j30elerm . Here is the problem. The former owner said it starts but does not stay running. It cuts out after it starts. He said he put a new power pack on it and it didn't change. I suspected a fuel issue. Tonight I thought I would look at the fuel pump screen and noticed something. The plastic cap that has the center screw through it has the screen on the opposite side. The screen is centered and held in place by a protruding plastic ring that is part of the cap. It seems someone had mashed it too tight when tightening the screw as the inner plastic ring mushroomed and a small piece of plastic from it broke off. It was not anywhere in sight and I suspect the only place it could have gone was into the hose that goes to the primer solenoid as the carburetor line is protected by the screen. Could this small piece of plastic be lodged in the solenoid and cause the motor to immediately stall after it starts ?

I got the motor started. It seems the gas can leaked out pressure around the guage. I used a can of mine and got it started and running. I now have to adjust the carb for correct idle and mixture as the previous owner turned the screws when he was trying to get it running . But it starts right up. Just have to fine tune adjustments . Any help on adjusting would be a great help .

Re: 1994 30hp part ID

I have a new question with this. If I put the red handle of the solenoid down in the "run" position it will not run. I have to move it almost 180 degrees . Is this an indication of a weak fuel pump diaphragm ?

Re: 1994 30hp part ID

yes the plastic piece could make it to the carb. also replace that broken part, it could be sucking air there.

I ordered a fuel pump rebuild kit. Could this be why the engine will not start and stay running if the solenoid is in the "run" position ? I have to keep it in the "prime" position . Weak pump ?

Thanks

Re: 1994 30hp part ID

pull the little fuel hose off the top of the carb, that runs to the primer. see in which postion fuel is flowing thru it. it should not have fuel going thru it in the run position, and should flood out the motor, if left in the prime position. if it is running in the prime position, you are not getting enough fuel thru the carbs.

Re: 1994 30hp part ID

Ok, it does only run when in the prime position. That is where it has to be for it to start and stay running . The more I put the red primer handle in the full prime position the higher the rpm's increase . If I drop the red handle back toward "run" the motor dies . So, if I am understanding this correctly it is pointing to a fuel pump problem ?

Re: 1994 30hp part ID

Or could it be pointing to another area ?

"if it is running in the prime position, you are not getting enough fuel thru the carbs."

Ok, after looking back over your reply I see the word "thru". So it sounds like the carb needs cleaned. Isn't there a safe cleaner made by Bombardier ? I have heard it is not wise to use carb cleaner .

Thanks
