Six Pack issues and rebuilding

[CudamanTom]

If it were a sticky I would link all the pictures to my photobucket account for more longevity. 
This is a frustrating experience for a nubee like me
Done lots of reading, and Chryco your Holley carb tuning guide has been very helpful

Sticky, Sticky, Sticky!!! 

And I understand your frustration.

Up to you on the brass, don't think it should matter one way or the other.

Hope this works out for ya soon so you can rip some rubber off those rear tires!

the squirters with the nozzles just get the pump shot further into the airstream. a very minor consideration for you. your problem is not in the pump cam or  nozzle. it sounds like you are flooding out. Are you still running an electric pump? have you checked the pressure? running a regulator? (personally I would run a mechanical pump) somewhere for some reason you are running raw fuel into the motor. either overpowering the float/needle and seat, or an internal carb leak.  don't know if a six pac will idle only on the center carb, but I would be tempted to block fuel to the front and rear carbs to eliminate them as the culprit.  then work on each separately. your issues have gone on way too long. good luck

I was fixing to suggest this..also block off the air to those two carbs so it won't go lean. Get the center one to run cleanly, then add a second carb and get it to run as well.  this way, you might isolate the problem and you will know when it is fixed

when I put my engine on the dyno, my builder started with the center carb only to break it in.  He has block off plates for the outboard carbs.  Tuned in the center, then added the outboards after is ran fine.  I can't help in any other way since my car isn't finished and running yet.  My carbs were rebuilt by a local carb guy, and they were spot on with the jetting.  I tried going larger, but lost power.  Went back to where it was set when I got them. Bummer this is difficult.  Might just be easier to get a set of new carbs from Holley and sell your old ones.??

Some great ideas worth trying. Block off the two outboards and disconnect the fuel lines.
It definitely acts like the engine is flooding.
My fuel regulator is allowing about 7 pounds. Dont think the regulator is the issue because the floats seem to be keeping the level at the bottom of the site holes. 

If I had known everything I would be going through 2 months ago I probably would have just bought new carbs and worked with them, but at least I've saved a couple bucks, and besides, look at all the fun I would have missed

Got home from work and decided to remove them....had all three sitting on my workbench in 12 minutes.
Getting better. Now just going to fit some plywood blockoff plates to the secondaries on the manifold, cap off the two fuel outlets and try with just the inboard, but... later... have to attend a funeral first

Do you have a power valve? Could it be blown flooding, run rich , run like crap?

Using a brand new power valve, the one from the kit. It isnt labeled but I assume its a 6.5
Any way to test it?

[CudamanTom]

Hey!!!
This is a sticky!!! 

[jhaag]

power valve should be stamped either on the end of the plunger or on the side of the body. I test them by sucking on the diaphragm side. should pull the plunger in closing the fuel passage way

[HP_Cuda]

Use the new stock 6.5 power valve you shouldn't have a problem at all.

Let us know how it goes plugging the secondaries.

Sticky status is 
I will link all the pictures to photobucket, but Im far from done here.
Today I spent an hour or so blanking off the secondaries with plywood and took time to clean the manifold up a bit. Tomorrow will cap off the fuel lines and try to start it up with JUST the primary. More pictures to come.

[tommyg29]

Ready to try to start it up again tomorrow.
Got my two pack thing ready to go, but first I cleaned up the manifold.

[HP_Cuda]

Dont forget to cap the secondary fuel lines!
