What on the 5200 goes to what?

[Anonymous]

Just got a 5200, or so i believe it is, it better be, heh, and there are 2 sets of wires, one that has 2 wires and another that only has 1, the one with one comes from the front left and the one with 2 comes from the back left and then i see something that i believe to be the electric choke and it is on the outer right side, and then there are all of the vacuum lines, i have no clue where any of these things go, if anyone has a diagram or anything that would help greatly, thanks

i'll take a pic tommorow, knowing my luck it is one of the feedback carbs

Hi RogueS,

I suspect you are correct. You are probably looking at a feedback unit. I'll be watching for the pics.

Sounds like the computer feedback carb from a mustang or Chevette. It will run but it's very rich. Has no powervalve and just dumps fuel. I can get you a standard mechanical carb but you would have to rejet it and change the powervalve to run on your six.

some pics, don't have any clue what the thing is in the middle that the first picture is focused on, the thing that has the big hole with the smaller hole set back inside of it

also don't make fun of the rope, lol, it has been doing its job quite well

Hi RougeS,

Pictures are well done. You did a nice job of using the generic (Stovebolt) type adapter.

As for the carb, I have not seen that version before. The early '70s 5200 has no electronics. The feedback version, the 6200, has a main jet metering valve that exits through the top of the carb. I have heard tell of a 5600 that was a cross-over version. What you have is not a 5200, as in "Stovebolt", but it I don't recognize it as a 6200 either. Sorry I can't be of more help.

Having said that, most of the electronic feedback carbs are designed to default to a standard / runable condition in the event of a module failure. So, if you don't wire the carb at all you may be able to use it. However, you will need to cap all of the open ports before you try to run it.

Next point, what appears to be your vac advance line is hooked to a manifold source. Is this the correct connection for your dizzy? If you want a ported source you can use the one under the choke.

Keep up the good work - Steve

That isn't a feedback carb. The feedback carbs have two wires coming from the top of the carb that control the metering of the fuel. As for the other wires, the one at the front appears to control the venting of fumes from the fuel bowl to a charcoal canister and then back to the gas tank through a return line, nothing to worry about. The only wire I would worry about is the one that powers the choke, unless it's a water heated choke which in that case means you won't have to worry about it either. Do yourself a favor though and get one of the cheap air/fuel ratio meters and install it to check to make sure your not running too lean. Holes in pistons are a bad thing!!

i don't have my vacuum advance line hooked up, the only tube i have hooked up is for the pcv which is hooked up to the carb spacer under the adapter.

i am still trying to figure out what the circled item in the following picture is

Where does it come out?

that is some emissions bs crap. I got a carb like that off a 79 turbo mustang and that port is unused. these carbs were also used on gms and mopars and one of them might have used that port for something. the plug dealy on the pass side nerar the fuel inlet is a switched vent for the bowl for a charcol canister so leaving it unhooked is ok. the feedback carbs are nice since a simple circuit can be mad to use a dial to makes fual adjustments. the solenoid that controls that is just like a mini injector and changing the signal will change mixture (fails rich). back in the day people did this for a drivers seat tunable car. they had a similar setup on 4bbl holleys called dail-a-jet I think

never thought about using the feedback carb that way, not too bad of an idea...
