Let me begin by saying I KNOW THE TWO BARREL INTAKE WILL BE A FLOW RESTRICTION. I am actually counting on that to help me out.

On my 86 van, I recently swapped to a Carter BBD from the stock one barrel. There is something wrong with the carb as it runs way too rich to the point of almost stalling the van out.

I don't have any other two barrels that will work without a lean burn computer, and my old lean burn computer has a blown vacuum pod. My solution? Use a two to four barrel carb adaptor and run a 400 CFM Carter AFB carb.

I am hoping that (1) I can adjust this carb lean enough easier than the BBD due to availability of after market metering rods and (2) the smaller CFM combined with the air door on the secondaries combined with the air flow restriction on the intake will actually help me get decent gas mileage.

What do you think?

I think you're trying to get from Seattle to Vancouver by way of Philadelphia!

There's something the matter—seriously the matter—with the 2bbl carb you have. The easiest and least-costly solution would be to get a different, better 2bbl carb and throw it on. Your proposed 4-onto-2bbl idea is going to bring many, many more hassles than are apparent upon first thinking about the matter.

(Also, you'd have a really tough time passing DEQ with your proposed setup, if your '86 is required to pass DEQ).

I think the fact that the flow restriction is past the carb will render the attempt a disaster. The carb will "see" a very minimal vacuum signal any time you get on it, and will have a hard time metering fuel correctly.

If I were you and were trying to just get up and running," I'd either

a) Try one of my lean-burn 2-bbls and see how it works- you might be surprised, and you can hook up a manual toggle switch to the enrichment solenoid to have a "rich" or "lean" control in the car.

b) Use the 4-bbl, but I'd just remove the linkage to the secondaries completely and let it run like a 2-bbl.

c) try to fix the BBD you have. Running THAT rich sounds like an incorrect float level, binding float, stuck needle valve, etc. rather than just being jetted too rich.

Jeez reed what happened to your 2305 Holley?

You could use a Mr. gasket 1937 and make it work with some of your elbow grease....

Dan is right on this one as usual. I had a street car /drag car with a sweet super six on it .Bought the four barrel adapter and Holly 600 cfm carb and the car slowed down. Of course this was when i was trying to learn slants. I would try to get a super six carb and get a good carb person to rebuild it. Here in Ga i know people that can rebuild carbs and they will work. Most rebuilt carb from auto supply houses are junk and money wasted. This is also why i learned how to rebuild Holly 4150 double pumper carbs because i use them. Hell if you can get on the internet you can rebuild a carb. Thanks Ron Parker

Say, isn't the Old Carb Doctor in GA?

*googlegooglegoogle*

Naw, never mind, he's in NC.

He is older than me but it is not the old carb doctor. Just a lot of knowlege about carbs. His sons rebuild my transmisions and Dales and Norms. Good Honest folks and know what they are doing. Priceless Thanks Ron Parker

I still hjave the 2305, and would love to run it, but vans have a rod style kickdown linkage completely different from cars. I have a idea of how to fabricate a throttle linkage and uyse the stock one barrel kickdown, I just haven't had time to build it.

Last weekend I tore the BBD apart again and double checked everything. The floats are set right, the needle is brand new, the metering rods are as lean as they can be set, curb mixture screws are only out two turns. I am at my wits end. I thought about reinstalling the lean burn computer and running a feedback Holley 2280 I have but I discovered that the vacuum port on the computer is blown so it won't hold a vacuum.

So I guess the adapter idea is out. Short term i am back on the hunt for a lean burn computer for a van (has to be a van to mount on the firewall correctly.

As alweays, thanks for the input guys! Its nice to be able to bounce ideas off of such knowledgeable folks.

Someday (soon hopefully) I am just going to yank this tired old motor and have a fresh one rebuilt and installed.

As far as emissions go, as long as it passes the sniffer I am okay. No visuals. They even use some kind of plug that goes in the cigarette lighter to measure RPM so the hood never even is opened.

Already have my nation wide part request submitted.

How about a "reman" from Carquest or NAPA? I just looked in the shop, but the one I have is for a newer Van. Even If CQ, or NAPA doesnt have one, available, they should be able to send yours out. I have done that when the rebuilders did not have the cores. They rebuilt mine.

Reed, what's the P/N on your module?

P/N 4289615 0426

I will check around at Napa and Autozone, but the last time I called around nobody sold it.

I figure that since all I am using it for is the air/fuel metering function and not the distributor advance curve I can use just about any lean burn from any year, but I would like to find one from a van just so it can mount in the same place (I don't have many places to mount things in a van since I don't have fender wells like a car does).

The first seven digits 4289615 are the P/N. I found it for you at www.autoecms.com .

Hey, thanks Dan! I sent them an e-mail asking how much they would charge for one.
