The Super Flow carb testing fixture is pretty similar to what Brad used, only it comes with a 4 hole spacer.
The spacer has a small hole in the center of it to locate it on the pin in the plate.
Then you just rotate it around to test all 4 holes.

The hole in the plate is 1.750, but the holes in the supplied spacer are only 1.687, which is fine if you're testing carbs that don't have a 1.750 throttle bore.

I found a spacer with 1.750 bores to use on the big carbs, and drilled the hole to locate it on the pin.

I also made one to use with 4500 series carbs.

Ray, could you pull 20.4" with flowing all barrels?

IDK. Im sorry but I have no idea.

I just threw my 1050 dominator that had the boosters changed to skirted boosters for e85 and it says it flows 1000.

Well, i just tried a 600cfm performer and it says 670cfm. shruggy

My method is probably not accurate but I would think comparable for me checking different carbs

You don't know what the test pressure is?

Edit:
Okay, I looked at the site where you got your electronics from.
The picture of the display box isn't all that clear.

Is one of the options for the display 20.4"?
If not, are you using one of the other depressions and converting the numbers to 20.4"?

Guys, I really dont think the way Im doing this is accurate. Im just throwing it on the bench with it converting at 28".

The TQ I have is 9379s. Pri 1.370

Edit: fast68 is schooling me on flowing carbs. My numbers are not accurate and he is making me depressed. lol
