Merc 40 Force - Takes forever to start

[racerone]

It is an enrichment valve shown in the parts book.-----Not the same as a choke solenoid that pulls choke flappers closed.

didn't say it operated a choke valve..show me where I said that....
I SAID it was called a choke solenoid that CLICKS and that's what the op should listen for....
It's also called an enrichment valve.....
one in the same........hope you can see the pics.....

I don't think he has a starter problem. As he says, he spins it over for 15 minutes before it starts. And it eventually starts. A bad starter won't spin a motor over for 15 minutes. And if it's spinning too slowly, are you thinking that somehow it gets faster after spinning for 15 minutes? If it was my motor, the first thing I'd do is remove the drain screws in the carbs and see if they have gas in them. I'd look at the spark plugs and replace them if needed. While the drain screws are out of the carbs, I'd pump the primer bulb and see if gas comes out of the carbs then. If it's taking that long to start, he may be having to get gas to the carbs with the fuel pump and the primer isn't doing the trick.

It is very easy to figure out why a motor won't start after 5 seconds of cranking.----Simple trouble shooting is a forgotten thing !!

Again test the primer.

these engines use a choke solenoid.....like these.....
should be an audible click when pushing the key in...

Hi again, i got a friend to listen with the cover off, while i turned to ON and pushed in the key. She definitely hears a click each time, so i guess it is not a bad Enrichment Solenoid valve. I will evaluate the Starter next. thx

 

[jlh3rd]

Good...I'm unfamiliar with how the valve is supposed to work, or if passages could be blocked........I just know the solenoid has to click........

 

[jerryjerry05]

The click means the key is making it click.
To test: unhook the hose from the carb and then push the key as you turn it over.
It should have a squirt of gas when the key's engaged.
If you unhook the hose and it squirts gas without the key then the enricher is bad. It has a rubber diaphragm that can leak causing it to flood and be hard to start.
Does it have a tachometer? In N in the water what's the RPM'S and in gear what's the RPM'S In gear N should be 1100+- In gear 750-800

thx Jerry. I was expecting you to say enricher is bad if it does NOT squirt.
To clarify, you are saying if it squirts when the key is turned but not pressed in, then enricher is bad, correct?

 

[racerone]

The enricher is a valve that opens when you push the key in.-----It is not a pump.

Correct

Hi Jerry, just tested the enricher. The first time, i had them just turn the key, and did not see a spray, then turn with push, i thought i saw a tiny squirt. But subsequent turns with and without a push showed no squirt. I am thinking all i saw was maybe some leftover gas in the hose. Regardless, the subsequent turns with press showed no squirt, so sounds like i need to replace the enricher.

 

[racerone]

The enricher only lists at $215 or so.----It must be the problem.---A new enricher will fix this issue 9 put of 10 times.

How is the spark? Maybe the spark is weak?
