Can anyone tell me where I can find the barbs for the carb vacuum port/s? I am slowly ironing out all the wrinkles in this 2000 250 Johnson ocean pro. Found that 4 out of the 6 carbs needed rebuild and did all 6. Now I would like to build one of the vacuum port test sets to dial the carbs in but need the barbs.

Thanks in advance for any info
 
First off your motor has 4 carburetors not 6. I know it has 6 float bowl assemblies & you would want to flow those 6, but it is not a carburetor until it has throttle butterflies. Your motor has two 2 bbl carbs up top & two single bbl carburetors on the bottom. It is important that you know this in your trouble shooting. The low speed needles are not that hard to dial in as they need to be somewhat rich in order to accelerate off idle. If you send me a PM (address) I can send you 6 - #327706 nipples if that will help. They are pretty small. I probably have some larger one that are 1/4 X 20" threads. Maybe something in between. I know what you want to do just not sure it is necessary. I can send a variety. Happy to help.

I really need a better Manual. I purchased the seloc online manual and it doesn't show or I'm looking wrong for carbs and float bowls. I looked at motor last night because I had to reinstall flywheel ( 2 magnets come loose so I had it repaired ) and I have 6 separate bowls and each bowl has its own butterfly. SoI looked and can't seem to visualize how they incorporated the carbs behind the float bowls with yet another set of butterfly's. It looks just like each float bowl is attached to a 3/4" aluminum plate with 6 seperate butterfly's that are located directly in front of what I'm assuming is a reed valve assembly for each cylinder.
 
Here is a shot of the carb assy from your motor. Hope this helps explain what I mean.
