I need the stock specs for a 17050213.

[Cadman-iac]

  I'm gonna try one more carb on this truck, but I want to make sure it's set up exactly like it was when it left the factory.
  Can someone please supply the stock specifications for this 17050213 please?
 Many thanks for your help, Rick.

 I mistyped the carb number, it should be a 17080213. Thanks

I don’t have the official book but have overhauled a few:
Primary jet 72
Primary rod 50M
Secondary rod DP

I've got them for a 17082213.  This was a "rear pull-off" carb that I pulled off a '82 Suburban in a junkyard.  It looked original and did not appear to be a remanufactured carb, but I cannot guarantee it.  I don't know if specs changed from 1980 to 1982 for a '213' carb?  I rebuilt it pretty much stock with just minor tweaks (secondary metering rods, and POE sizes) and ran it on a mild 396 for a while.  Seemed to work OK. 

Here is what I measured for stock specs:

  Thanks for the information, I see that my jets and rods are a match, my secondary rods are aDR though,  not sure if there's much difference, gotta check Cliff's  chart.
 Much appreciated.

… let me know if you need the other specs(bleeds) and what not.

Here is what I measured for stock specs:

Yeah, I don't know what differences there were between the years either, but given that the emissions standards changed every year, there's probably something that's different between them, but who knows what.
 This was a dual pull-off carb, but I changed it to just the front and made another one of those brackets for the air valve stop and changed the shaft for one that uses the front pull-off.
 Not a fan of the rear pull-offs, too big, hard to adjust the rate, and they stick out in the way on a lot of vehicles.

 I wonder if the idle discharge ports and the bypass sizes are the same between these?
 I measured mine at  .054 for the discharge ports, and  .055 for the bypass air. Quite a bit of difference.  Now I've gotta wonder if the base plate has been switched.

 My idle tubes are  .028,
DCR'S are  .054
UIAB is .069
LIAB is  .062
PAB is .051
Nozzle bleeds are  .029
Jets are  #72
Rods are #49M
Accel pump nozzles are  .025
Secondary rods- DR
Hanger is an N
Sec. bleed tubes,  .026
Sec. well holes,  .039
Sec. accel nozzles, .033

 So it's close, but is it right? I have no idea.

  Thanks for checking all this, I definitely appreciate it.

 Yes, if you don't mind, let’s see what you have. I want to be sure this is as close to stock as possible before I use it to test the truck.
 I don't know if this is a carburetor problem or if there's something wrong with something on the truck.
 This will be number 4, so if all 4 show the same results, I seriously doubt it's a carb issue, and I'll have to figure out what else it could be.

 Thank you for taking the time to help out.

Air lid:
Main bleed/single….051”
SPOE….046”
Emulsion tubes ….026”
Acceleration discharge holes…026”

Main body:
Idle tubes…031”ish
IDCR….055”
LIB….062”
UIB….069”
Well jets ..039”

Baseplate:
Idle mix….062”ish
Idle bypass….109”

  On your measurements, you are listing  SPOE at  .046, is this the discharge holes in the front of the secondary barrels just above the air valve?

 Something I've noticed just the other day is that these holes are bigger where they open into the barrels, but if you check farther down inside of these holes, they step down in size, I think that's the actual restriction for the secondary pullover enrichment system.
 I've always just checked what size the openings were, and I've never had any match with the specs. So I probed with a thinner wire inside of these and I could feel it hitting a ridge. I also pulled the tubes to be sure I was getting all the way down the hole, you can see your tool in the hole for the tube when it goes in far enough.

 The main body measurements all are either exactly the same or just the tiniest bit of difference, which is great.  The air horn measurements are the same way. The base plate is what's off, so I think this one must have been switched out at some point.

 Again, my thanks for taking the time to do all that.

This is what i have on the 1980 350 HD Truck 17080213 Rochester and Carter units.

  That's very very helpful, thank you Kenth. So it appears that the base plate has been switched, but with this information I should be able to set it up correctly. I've already drilled the mixture discharge ports to  .108, and the bypass air is not hard to change.
 Your list explains the differences between what MCX and Novadude have provided and what I've measured. This looks like a combination of both Rochester and Carter. I wonder if it's a high altitude calibration.
  My thanks to MCX, Novadude and Kenth for your help with this, it's much appreciated.

[Cadman-iac]

 Correction: I've already drilled the bypass for  .108 set screws, the idle mixture holes I've still got to size to  .086.
 I was just rereading my post and realized I put in the wrong information.

[novadude]

Based on Kenth's info, it looks like the 17082213 and 17080213 are pretty close.  What I have listed as POE for my 17080213 are the discharge holes above flaps.  For some reason, I did not document the well re-fill holes.

 True, I don't know if it would matter if I used either of the specs as long as they're all from the same carb.
