What the Heck is This ?? ( Shrader Valve on Choke!)

[milmat1]

I have to crank the cold engine forever before it starts, Once started it will fire up instantly all day long. But on a Cold Start it will crank forever before it fires.
So While trying to troubleshoot the electric choke (Enricher) I ran accros this valve. It is a Shrader valve and has a two position red lever !!

Question is What the Heck is it for ? Does it have to do with the hard starting problem.....???

Re: What the Heck is This ?? ( Shrader Valve on Choke!)

Well I checked the Voltage to the electric choke unit. And when I press the Keyswitch I have voltage to the Choke solenoid,. From what I can tellth the Carbs do not have an accell pump, So it relies strictly on vacuum to get the fuel in so pumping the throttle will do nothing.
If it were a fuel pump problem I think it would show up all the time not just during a cold start....?? Hmmmmm Keep Looking for now...Still dont know what the heck that Schader valve or lever is for....?

Re: What the Heck is This ?? ( Shrader Valve on Choke!)

For starters, your motor doesn't have a choke - that's a primer/enrichener. Press and hold the key in when starting. Tease it a few more times 'til the motor warms up. Don't worry about the red lever - only turn that if pull starting with a dead battery.

The Shrader valve is there for winterizing purposes only. They make a fogging oil can with a thread-on connector that goes to that valve - saves removing the carb cover and spraying it down the throats.

I dont think the enricher os working. When cold starting it goes like this:

Crank for several seconds, stop.let starter cool.

Crank for several seconds again Stop and let starter rest.

When it eventually fires, It will run only for a second, Try again several times until it Runs. Like it is getting No Fuel at first. However after this cold start it will start instantly all day long without even re-pumping the Bulb...

Strange !!??

Think I'll remove the lines from the enricher and clean everything real good and see if it helps...

only turn that if pull starting with a dead battery.

Which way is the normal position ??? And I dont have a pull starter....??

Re: What the Heck is This ?? ( Shrader Valve on Choke!)

The way you have the handle is correct for normal operation.

The primer solenoid is just a valve, so pushing in the key does nothing unless you have pressurized the fuel by squeezing the primer bulb and/or cranked the engine to run the fuel pump.

When you do push in the key, you should hear the solenoid click. If it clicks and you still do not get pressurized fuel to flow through, you may need an inexpensive rebuild kit for the valve. http://www.iboats.com/Evinrude-Serv...0661775--**********.406991175--view_id.507812

Of course you have a pull starter. It is called a rope with a wooden handle. You wind it around the flywheel. I had to use mine a few weeks ago when I got caught with a dead battery. And I didn't even have the original rope, but used a piece of docking line. Started on first pull (warm).

In your starting routine above, you never mention pumping the primer bulb or pushing the key in to work the enricher. If you're not doing it, you should:

pump the primer bulb until hard. If you don't do this, there won't be any fuel up where the enricher can use it.
turn key to on position (don't crank)
Push in key to run the enricher to get fuel into the cylinders. Hold for at least 5 seconds, longer if necessary
Crank engine, it should fire.

As mentioned, you might have to tap the enricher to keep it running.

I think thats exactlu what I need, This one does nothing when hit with 12VDC, And after removing the cover it appears to be packed with some type of harder than Heck trash. So the Spring and plunger wasn't even visible. Dont know what got in there but I hope thats the only place it was !!...Thank You for the Link !!

I should have been more clear, Sorry. I do use the Pump Bulb and the Push/ Enricher but it just wasn't working. I Found it full of a Hard crusty Substance that looks like brown Glue !! The Spring was completely encased in trash !

I removed the cover from the air inlet box, And there is No air filter in the motor at all. Geezzz Does this Ever End ?????......LOL



Thank You For the Help Guys !! I'm pretty new to Outboard motors and I'm finding they are a different animal for Sure !!

There is no air filter on these motors, it's just the air silencer.

Yea, Thats what I have discovered trying to find one. That is quite strange to me, I Suppose the thought is there's not must dust on the water....!

I did find all the parts to rebuild the Primer/enricher, This one is trashed !

Re: What the Heck is This ?? ( Shrader Valve on Choke!)

Dragging up an old thread, I know. I am experiencing this:

1996 90 HP Evinrude. Always started fine. Lately though, it will not start unless I yank the cowl off and turn that little red plastic thing near the solenoid.

If I push in the key, I can hear the solenoid click. I pulled off the little plate that the schrader valve is part of, then pulled out the little rubber diaphragm. If i push in the key, I can't see the little white plunger moving. But if I apply a little pressure to the plunger and hold it in a little bit, if the key is pushed in I can feel the plunger actuate.

Based on this thread, I assume I order that rebuild kit. However I can't for the life of me see how it will help though. Everything I looked at when I pulled it apart looked clean as a whistle.

Thoughts...insight? Thanks

If the solenoid is not working properly, replacing the valve will not help. Check the wiring and voltage to the solenoid when you push in the key, and make sure that you have a good ground.

I'm getting 12V at the bullet connector on the purple wire, and am using the same ground point that the black wire on the solenoid attaches to.

The thing is, I can hear it click, and I can feel it move slightly if I hold the plunger in a little when I turn the key. I guess I just don't know how much or how far that little white plastic tab that is part of the plunger is supposed to move.

Re: What the Heck is This ?? ( Shrader Valve on Choke!)

I have a new to me Johnson 40 HP and am having the same starting problem. I really haven't cold started it enough to figure out a good dependable starting procedure yet. It is a little embarrassing to leave the dock each time powered by my 4 HP kicker. But my kicker is a 1971 Evinrude so I'm kind of proud how after all the 40HP cranking, I drop the 4 in the water and it starts on the first pull of the rope.

So when your motor does fire and stay running, do you find it smokes excessively for the first few seconds? Mine does which leads me to think the primer is flooding the cylinders rather than not working. I certainly hear mine click when the key is pushed in. Also I only get this condition when it hasn't been started for a few days. After it fires up it starts perfectly for the rest of the day or weekend for that matter. Best of luck. Rick.

Tried a rebuild kit, no change. Time for a new solenoid?

Re: What the Heck is This ?? ( Shrader Valve on Choke!)

On the primer there will be 3 fuel lines, 1 IN from the fuel pump and 2 OUT to the intake manifolds.
Disconnect the 2 OUT ones, have someone push the key in to activate the primer & pump the fuel bulb. Fuel should come out of the 2 disconnected lines when the primer is activated so have some rags handy.
