There is a air bleed inside the venturi behind the vacuum diaphragm,if you look down inside you will see a small hole cover it with you finger and the diaphragm tube at the same time,it should hold vacuum.On the float level,you will notice the sight plug is higher on the center carb,you can go higher on the ends but will probably have a problem if you go much higher on the center.Just finished this set,sight plug location is very easy to see.

Date code on bowl is 82.

Next post has air bleed location.



I'll cover the bleeds today and make sure the pod to body seal is holding later. Using the sight glass, I set it to just be visible, afterwardds when I removed the sight glass to put the plug back in it didn't dump a lot of fuel like one that is set high either. The base float set up I have always heard and used on a center pivot you set the top of the float parallel to the top of the bowl and then adjust on the car running. In the picture my bowl isn't close to parallel.

Set the fuel level with the engine running, for starters bring the fuel level up to the bottom of the site plug hole, I too like to use the clear site plugs, as I bring the center carb fuel height up to the center of the window, for street use just at the bottom of the site plug is fine, if your going to throw the car around a road course/track event, then that's when I bring the fuel level up to the middle of the site plug on all 3 carbs"new" Holley clear site plugs suck!, as you found out earlier, they just dissolve with fuel and soften up, the Moroso clear site plugs I have heard from another member are much better if you want to keep them in, all my six pack cars run clear site plugs, fortunately I bought a number of them years ago, but a recent set (Holley) I bought for a 4bbl application lasted like 1 day before the suckers snapped off!


Anyway here's a closer pic of the air bleeds mentioned earlier (not a six pack carb, but still a Holley for reference)
