‘99 4str 9.9 Evinrude carb?

[Rabbit929]

Recently had REALLY hard start issues e10el4eeb model number.
cleaned up the carb, now something got stuck in the main system. So I gotta do a full rebuild.

there is a jet, right in the middle of the flor on the bottom side that’s not on the exploded view diagram? (No I am not talking about the float needle and seat)

the previous owner has this jet so tight it snapped, and now I’m gonna have to drill it out.
anyone have any idea what this part is?
or know of a different carb that will bolt up to these motors?

It’s the one in the middle, which would be surrounded by the Float. It also has a small needle in it, what jet and needle would this be called??

It is the main fuel nozzle, and it has a needle that goes into the side of it, you can get it out thru the drain plug hole. I never remove the nozzle itself, just the needle from it. That part is not included in the kit, and I do not think you can purchase just the nozzle. (May be called a nozzle well on some views if you can find it).

I would look around for a scrap carb for the same motor, and just use the housing from it so that broken part will be in tact and use your rebuild kit in that housing. That would be cheaper I believe than trying to find a good used carb or a rebuilt one somewhere. Look on E-Bay or local motor repair shops for a carb body you can buy.

Thanks for the input, I just got off the phone with a carb professional, now from what he said is the part he doesn’t believe is even removable. He thinks it’s most likely Loctited in, and he has no idea why it’s even grooved for a screwdriver in the first place.
any attempt to remove it is likely gonna turn your carb into a brick.
the motor is made by Suzuki but branded Evinrude, and basically if I can extract it intact enough, a machinist would be the only other option of getting one.

so hopefully, any of you with a similar motor, touching this jet or needle is the only thing separating your 1999 9.9-15hp 4 stroke from running, or becoming spare parts.
I happened to score a new carb, the only one I could find as every salvage yard I’ve contacted said they’ve already been cleaned out of these carbs.
sad that a 20 year old motor could be put to rest so easily over a simple carb.

I would double check if that is a suzuki or not. Johnsons were a Suzuki product but some of the Evinrude 4 strks are OMC made. And that looks like an OMC carb not a suzuki. I could be wrong Get Racerone to answer he will know for sure.

OMC?
I looked up the carb, and the carb is the same for 98-01 (at least) for Evinrude 9.9s
i looked up the same year (99) same specd motor for Suzuki, and the carb looks very different?

Why would you say SUZUKI built these ??-----The lower unit is the same as OMC 2 strokes with a different driveshaft spline at the top !!----The carburetor is essentially the same as the OMC 2 strokes too.----You are right they are not well supported for parts today.----I have 3 of these orphans for parts at this time.------Newer Johnsons were a SUZUKI built item.------I also have a 97 SUZUKI 15 HP and it is totally different from the EVINRUDE / JOHNSON models of 1995 to 2000.------On outboards everyone seems to jump all over the carburetor for the first step in trouble shooting.----What other trouble shooting was done for the hard to start condition.----Was the electric primer checked if equipped with that item ?

I’m a mechanic by trade, though usually do industrial work. Yes, the primer is functioning well, fuel pump tests good and fuel lines and primer bulbs have all been replaced.
my problem was a lack of air in the idle circuit, so essentially it would flood while cranking.
I cleared the obstruction, and it started great but wouldn’t rev. Meaning the obstruction I just blasted out of the idle circuit is now in the main. Rich/flooding condition.
most of my used engines the first thing I do after running it is usually go through the carb, however this is a first with a main jet being a non-removable part.
by no means am I a carb professional but this main jet appears to be loctite’d in, and is only sold preinstalled in a complete carb. Which is why it’s not on the exploded view diagram.

long story short, any attempts to remove this, as a seasoned outboard mechanic informed me, with essentially brick the carb.
ifs a booby trap.

But item #23 is the main ( high speed jet ) screwed into the carburetor !

That is correct, it screws horizontally into the Venturi on the left side of the photo.
the jet and needle down the center are the ones I need, which is the main. The main jet is not a replaceable part is what I’m getting at.

That item is a NOZZLE and not the main jet , also needs no brute force maintenance.-----The VENTURI is the restriction in the carburetor throat !

I saw some used ones on E-Bay that would fit your motor, and they were all abut $200, but you don't know what condition they are in when you buy them. Saw one that said it was rebuilt for $300.

edit: I would think that nozzle is a press fit and not loctited in, but that is my guess.

*main jet nozzle* is what the outboard carb guy referred it to.
Is there a point Your trying to get to??

 

[racerone]

Best bet is to find a used carburetor on E-Bay.
