Carburetor Problem 3.0 glp-d

[naumovski]

First of all i had a problem with my carb running rich and i decided to rebuild it...
I have a problem with identification of my carburetor..
I have 2006 3.0 Glp-d and a Holley carb with all this numbers on it
1223,2285,75028-2,3863240,3250... I ordered a rebuild kit from volvo penta store
but i think thats not the correct one because the diapraghm and some other parts in
kit are not the same one...And i had one more problem that the previous owner of the boat
already rebuild the carb so he changed the main jets,power valve and nozzle so i have no idea what size are the standard jets on
this 2bbl carburetor and what size is the power valve and the pump discharge nozzle size?
If someone with the 2bbl carburetor and same engine can tell me about STOCK size of a power valve,main jets and nozzle
or if someone can tell me which carburetor kit is for my carburetor model??
THANKS

Re: Carburetor Problem 3.0 glp-d

The List number for the Holley carbs can be found on the right side of choke air horn or on the top of the main body casting. Below the list number is a date code.


Look for the numbers on your carb and then search for it on the volvo penta parts website- seems you might have carb 3859065 so it looks like you need kit 21533394.

Or, research your engine here - Marine Gasoline Engines for 3.0GLP-D - 7744800 - Volvo Penta and then look at the carb rebuild kits.

Sorry I can't help you on the stock components but if you can post the model # of the carb you have, I'm sure someone can cross reference the jets/powervalve/accelerator pump size you should have.

Thanks for reply
I wrote all the numbers that i found on carburetor body and i cant find any information on internet and i already dissasemble it...
I ordered the same kit that you mention 21533394 but the diaphragm its not the same and also some other parts in the kit...I have no idea what is the size of the power valve in the carburetor because it is not the stock one and it not have a number on it..Main jets are with numbers 702,711 and they are not stock also changed from previous owner...Pump discharge nozzle is 36 and i have no idea if it is stock one...In my rebuild kit the power valve is 2,5 any suggestion if that is good for 3.0 and the diaphragm is higher than the old one in carb...All gaskets are correct...Any suggestions what should i do with the power valve main jets and nozzle...Because the boat was running too rich..If someone with 3.0 can tell me the stock numbers that will be my start point...

Check with the parts department at a dealer.

X2 on contacting the dealer.
If you don't want to do that get the model number of the holley carb and call Holley- tell them what you are doing and see if they can give you a recommendation for a starting point. Jets are cheap and can be purchased at just about any auto parts store.

here - Link I used when tuning my Jeep's carb. I'm sure the boat has some differences but at least this will get you headed in the right direction.

Re: Carburetor Problem 3.0 glp-d

I wrote a mail to holley tech and they tell me that they not have a kit for this carburetor..
And they not have more information about this model just wrote to me
75028-2 is a model 2300 2 bbl marine carb
a kit for it will have to come from volvo penta
But the kit from volvo that i bought is wrong...
And everything from valve,jets,nozzle etc was changed in carb so i have no idea what to do??I would like just to know the stock specs?

Thank Don
This is my first carb rebuild so i am trying to figure out everything...
One more question please..
I had eletric choke and it was set on the center notch where the mark is,
and here on specs i read 5 notches lean..
Can someone explain to mean what that 5 notches lean mean because if i
turn the choke 5 notches from the center mark it will come to the last notch
or?
And i noticed that fast idle cam the plastic one have a lot side to side move and when i move the choke sometimes its binding up and the choke left just a little bit more opened...Any suggestion?
Is that ok or?
binding

Re: Carburetor Problem 3.0 glp-d

That is one of those settings that can be set any way you want it. Not sure what they meant, lean air or fuel. May even say on the choke cover itself.

What I do, when setting an electric choke is to move the throttle lever off the idle cam, turn the choke cover to close the choke plate. Then when the choke plate just closes, go maybe one notch tighter.
The factory setting usually is way too tight and the engine belches out black smoke from running really rich a lot longer than necessary.
If you decide you want it a bit tighter, go another notch tighter until you feel comfortable with the settings.

When you start a cold engine, you should be bringing the idle up to 1000 to 1200 rpm until the engine warms up and will idle with the choke open.

Thanks Don for your reply
So for now i will let the choke like it was until i will start with tune up process..
And i just want to ask one more time if anybody have solution for the fast idle cam..
I noticed that fast idle cam the plastic one have a lot side to side move and when i move the choke sometimes its binding up on and the choke left just a little bit more opened...Any suggestion?
Is that ok or?It is a good idea to grind the plastic a little bit or?
