hello I'll try to keep this short.Do I rebuild or find a different one? I have 17086047. Eng is 350 +30, proformer intake, Alu 202 heads, 224/230/110 cam and 2"ram horns on my 72 C10. I have cliffs book and am still a little confused about the rebuild but what the heck. Thanks for the help Ken

Looks like a fine carb to me. For your cam you'll need to richen up the idle circuit a bit, and it'd probably be wise to re-calibrate it with some advise from cliff on jetting. I'm not sure if that's a single MAB or dual MAB carburetor.
-
Thanks Shark. I am hoping to be directed on what parts to use as this is new to me. Also when I buy the kit does it come with directions or is the book good enough?
-
Cliff's kit will come with a few sheets of info on basic procedures. Get Cliff on the phone and he'll be able to give you good advice on parts.
-
I took the carb apart and I dont know how the secondary holes come out ? It looks like one is out of round. Do you do it with a sckew and pull them out ?
-
Do you mean the secondary jets - at the rear of the float bowl?
-
yes if there called jets ? Thay dont seem to screw in like the primarys.
-
the little discs in the back of the fuel bowl should be about .135 they do not come out .( im not saying you can take them out) leave them in. some times one will be a little out of round from the metering rods flopping around. they are not intended to seal .they just control the amount of fuel the 4 barrel gets , depending on the rod size and hanger length and secondary air flap opening .i hope im not confusing you .
-
Thanks for input. That was my worry one of the holes is out of round. The hanger looks bent. I'll buy a new one (hanger)when I buy the kit. It sounds like it should be ok because the truck will be a daily driver.
-
Hello. After thinking about it I cant get past the idea of leaving the secondarys like that. I'm going to find a different carb. Thanks All for the help.
-
There are definitely replacement secondary discs you can buy.
-
Hello, I am going to buy all the parts I need from this site because of all the support I am recieving. So far I have tore down and cleaned most of this carb but how do I replace that disc (secondary)?
-
The disks go in first, then you drive a retainer in over them. Pretty easy install.....Cliff
-
Hello, Is it just a matter of prying the old ones out or is there a special way to get them out?
-
I used a 2inch 10-32 and a slide hammer and out they popped right out.
now to get my list of parts together.
-
Good luck finding a replacement the correct size. The only source I've ever found for them was quadrajetparts and theirs
Are about .010 larger than stock. Ii wound up salvaging some from a donor carb.
-
I have a parts carb that is near useless to me at this point. I'll gladly send it to you for the price of shipping. I think the discs are fine but can get pics. Let me know.
-
I just finished installing the secondary discs, they did go in pretty easy but I should have centered them before seating the retainer.
-
Hello Sorry about the last post its in the wrong spot. K.E.N.
-
How about that ,this post has two pages. I posted that I instaled the discs then couldn't find where it went . I used the search to find it and thought it was hunters post because that was at the top of the page. turns out that it was where it should be in the first place. I'm sorry about the confusion. I have to go now my finger is starting to bleed.

I will definitely have to try this method on my carb.

Hello, Well its together. I need to take it back apart to add bypass air. I didn't think it would need it but its good to see this stuff and learn as it happens.
