If the holes are that small (7/64" -1/8"), it shouldn't be the problem. I've been thru all that with my carbs. You got to get the center carb plates to CLOSE....all the way. The butterfly's must not be straight in the bores or something. Like mentioned, you should be able to loosen off the little brass screws a tad just to get the valves to loosen. And are you absolutely sure the end carbs are not open a tad as well..... Hoping to see you get this ironed out and go have some fun...

Update as I just got done working on it.
Well now I am really getting frustrated as it will not start yet. I have replaced the ecu with chrome mopar one, the resistor with MSD .80, and the fuel pump with a 150 gph mechanical pump. Still did not start. I checked the coin for spark, it has a big spark and about knocked me on my butt as it arched across the metal and came back and hit me! then I pulled a plug wire to make sure it had spark at the plug. Yes it had good spark there. Poured a little gas in the center carb and it fired off.
My only other thoughts are the fuel filter or the sock inside the tank?? I am going to pull the filter tomorrow it is brand new "date code" correct metal one. Has anyone had any problems with those??

now you know whythe "shock" people back to life. I'm guessing you have a blockage someplace. Run it straight from the can and see what happens. I had an issue w/ a blue gasket covering a tiny passage in the primary that gave me all kinds of fits.

Maybe i should start my own thread but: my six pack hasnt been running super great but i found that the intake was sucking oil so fixed that yesterday.i also tested the outboard carbs with a vaccum pump to make sure they open and they didnt, i used the vac fitting/line that connects all three carbs together,is that the right one?
Do them individually,if you go off the center port on the Tee,if one leaks you won't know which one.

I agree with the above and will add this to hopefully clarify what he is saying, You have an Ign 1 and Ign 2 circuit. Ign 1 bypasses the ballast and applies full battery voltage to the coil for a hotter spark when starting. Ign 2 goes though the ballast resistor to limit the current through the coil and prevent overheating the coil. This is a short summary not inteneded to cover the why fores of why it is what it is. In short ( no pun intended) if it starts in the CRANK position and dies when releasing the key to the "run" position you are not getting voltage to the coil. Look for a disconnected ballast, (Easily done when re sealing an intake), or a bad ballast. Could be a bulkhead problem, ignition switch problem etc. The most likely candidate is the ballast or connections to it. To Confirm, Jumper battery Voltage to the coil, hit the key, if it starts and runs your halfway home. UHH do not run it this way for an extended period. you May have to pull the Jumper to shut the motor off. Report back

Is the ballast directional?

Pulling a vacuum on the outboard carbs, whether in a pair or individually is quite different than pulling say: vacuum on a brake system pulling fluid thru a line, the end carbs will only open and stay open with a continuous vacuum source, every time you stroke that mini vac pump the diaphragm's inlet lost the vacuum pull, your better off just pulling a vacuum using your own lungs, either disconnect the linkage from the center carb, or open the center carb to WOT when doing a test of the outboard diaphragms, if your diaphrams open fine, doing a "static" test of them, but still aren't opening under throttle conditions, and you know the end plate throttle blades are not sticking when closed, then either you have the center carb vacuum advance port hooked into the system, or the outboard diaphram springs are too heavy, I like to start with the white springs and work my way up the color spectrum rather than working down from the factory black springs that are often installed in replacement six pack carbs

Please clarify what you mean by ".... I can not get it to idle below 1000 as we are bottomed out on the idle adjustment ..."
Does this mean that the throttle plates are open as far as possible with the adjustment screw at 1000 rpm, or are they in the closed position?
When at an idle in neutral, if you put you hand over he middle carb to choke it, does the idle speed increase initially before dropping off?....if so, it could be a vacuum leak.
If I can give my after I've adjusted the center and outboards (promax baseplates installed) advanced the timing to where is really healthy, and vacuum is at 18 I'm idling around 1400rpms and I can't get the curb idle screw to get any lower the maybe 1200.
