You need to give some thought to the desired outcome......before cutting. Generally when you cut down the divider on a dual plane manifold, it adds a little top end but softens the low end. If the engine is in a heavy car with tall gearing, it might hurt overall performance. And vice versa.

I have found that you can generally re-use the gaskets on these carbs if you are careful with disassembly & do not rip them.

Uhhhhh. Yes & no if you are referring to the AFB/AVS models. Edel copied the the Carter & many parts are interchangeable. You could swap the top of the #1406 Edel carb mentioned in this thread with a Carter #96XX carb, & both will work as they did before. There were changes in the boosters, but...

Carter fuel pressure/float setting. Note 10 psi.

Dmopower, Post #26. The more you post on this, the more you show lack of knowledge: - fuel level can rise [ seep ] for other reasons than trash. Improperly machined fuel inlet seat, deformed needle, needle a sloppy fit, excess pressure & leaking gasket can all cause the problem. -...

Dragtop, You probably didn't get lucky by not having a reg. The FACT is these carbs will handle 10 psi. I will see if I can up load the Carter chart that says so. I have run 9 psi at the drag strip, zero issues, as a quick test to slightly richen the mixture. [1] Carter recommends on all...

DM, You can postulate all you like. Everything in post# 11 is true & correct. Page 9 of the Edel tuning guide states a fuel starvation issue could be caused by low fuel pressure & 4-5 psi is reqd, MINIMUM. NOT MAXIMUM. Further, Edel carbs come with the small 0.093" n/seats. The comp...

The Edel carbs are NOT sensitive to fuel pressure. The fuel system is a DIRECT copy of the original Carter AFB design, which was designed to use up to 10 psi of fuel pressure. Carter even produced a chart for tuners to set float level/fuel pressure because one affects the other. The reason Edel...

The problem is the acc pump plunger cup. It will dry out & shrink; when the carb is re-fitted, no pump shot. Best to loosen the air horn screws & dribble ATF into the pump chamber to lube the plunger cup.

Vaseline or ATF for lube, both compatible with rubber.

Love hearing TQ stories, but would like info on my specific question if anybody has some.

I have 850 CS TQs, one with screw in jets, one with push in jets. Both have a brass tube in the rear of the carb for the air valve diaphragm hose. This brass tube has a very small hole in it, about 0.015". It severely restricts the release rate of the diaphragm & therefore how quickly the AV...

Mopar 38. Not sure if you are asking....or...telling....

And?

71 GSS, Your post #107. Sorry for the delay [ time difference ]. The quotes you need are in posts# 19, 27 & 53. I thought I had included the info from Holley engineer, Mike Urich. Couldn't find it, might have been thinking of another thread. P. 23 of the Holley book: 'The strong...

71GSS, Post #104. I have provided two quotes earlier in this thread [ referred to in post #105 ] that that show a smaller MAB starts the system the earlier. A larger MAB will lean the mixture at WOT, not richen it.

RB/TT5, I have posted TWO quotes, one from Holley engineer Mike Urich & one from Dave Emanuel's Carter book that state that a smaller MAB starts the system sooner. That part of it is simple high school physics, as shown with the straw example. Despite all the blustering & hoo-ha from RB...

Well you didn't say that in post #87... You just said the MAB starts the main system sooner. No mention of the MAB being bigger or smaller. That was what I was querying.... Oh, & I am following....& I have had real world experiences as well.

T55.9, Post #87. The MAB starts the main system sooner. Compared to no MAB? Not following.

92b, Post #86. You get it, go to the top of the class & get your gold star..... A lot of people on this thread are talking about fuel flow after the main system starts. It has to have a starting point. The straw/liquid example describes the system start up perfectly.

71GSS, Unfortunately in your post #68, logic is missing from the first three lines. If a larger MAB starts the mains sooner [ it doesn't ] & flows more fuel, then it follows using the same logic that increasing the MAB will increase the fuel flow even further; not stop it as you say...

RB, What I know is what it says in post #58 & it is correct. Same as what I have said. Tom Vaught [ not Vought ] is a university trained engineer who worked for Holley during the glory years, & then spent decades at Ford before retiring. We correspond via email. He told me Mike Urich, Holley...

RB, Nope, still getting it wrong & Shrinker doesn't agree with this fact: a larger MAB starts the system later, not earlier. If you bothered to read post #58 fully, you would have seen the straw/liquid experiment mentioned, which I posted waaaaay back in this thread. From post #58: ' A larger...

RB, You know what Tuner says? So do I, I have read it. And it is NOT what you say he says. Why don't you tell us all about pressure differentials at low air flows???????????????? I am sure DV would like to know as would many others.....

Nope, not wrong & neither do Shrinker/Tuner say I am wrong. Quote where S & T say: a larger MAB starts the system sooner. From D. Vizard: [1] His Holley book, p. 86: ' ..changing the size of the main cct high speed bleed changes the slope, so if the mixture is leaner at the top end, reducing...

Post #45. ' Larger air bleed starts the mains sooner '. Nope. When RB quoted the info from post #41 into his post #45, he got it wrong. What post #41 said: ' With more air coming in the bleed...'. A vital but important distinction. What causes 'more air' to come through the [ air ]...

Demon, Your understanding is correct about creating emulsion. But emulsion is getting mixed up with when the system starts & the relationship THAT has to the MAB. The smaller AB starts the system earlier & vice versa.

Aww shucks..... We are only at 38 posts. The UT/DV thread is over 580....

I don't need to read what I wrote because I know what I wrote'; nor do I need to read Taylor. You asked how does emulsion ABOVE fuel level functions.....& I answered it.

I am quite happy to have a civilised discussion with you about emulsion. I am not sure what you mean by function of emulsion above the fuel level? The entry to the booster is 1/4 -1/2" above the fuel level in the fuel bowl, for all venturi style carbs & this is the theoretical level in the main...
