3duce set up Ford 94 carburetors

reddog565, I would hate to tell you how much I have in my car. It cost me 4800.00 just to have it shipped to Alaska from New York state in an enclosed container. on a side note, I am originally from Pa. , I was born in Lancaster, my mom and dad and their family's are from that area. my dad was military , so we have lived just about everywhere. what kind of vehicle do you have and what size is the eng. give us a little info on it. unless I missed it in another post I do not know what you have.
 
I am retired. I was a self-employed truck driver for 45 years. My car is a 51 Ford F100 rat rod. It has a 272 Y block.I'm not that computer literate. I need to take some pictures of it and resize them and I'll send them to you when I get a chance.
Thanks for staying in touch....

Hi sal. Thanks for joining the conversation! I believe you're correct when you say motorcraft has larger Jets. I think that's what this carburetor shop was referring to. He told me from the mid-60s on that they change the size of the threats. So anyways! You have any good leads on# 55 Jets. I don't want to cut into your source.
 
Thanks sal! I don't know if you read about the issues I've been having with these carburetors?
But since you been doing them since your 17. what's your thought on my lean condition?
 
I really don't know why your engine is running lean if the center carb has #52 jets and you did install block off plates on the front and rear carbs, other than a vacuum leak which you've already looked for and couldn't find. Without being there, all I can say is if it were my engine, and I was starting from scratch, I would keep #52 jets in the center carb, and on the front and rear carbs use a power valve block off plug, and seat the two idle mixture screws. Then put about #55 jets in the front and rear carbs because of the blocked off power system. Also on the front and rear carbs you need to completely close the idle speed screw until the throttle plates are seated and sticking in the bores. Then turn the speed screws in until they just contact the throttle lever, then a wee bit more (less than a 1/16th of a turn, Just enough to keep the plates from sticking in the throttle bores. Also need to make sure there is some type of return spring for the front and rear carbs too. This is assuming you have progressive lnkage, which it looks like you have.

Can you borrow a carb from someone that has a good running engine? If your engine still stutters and staggers with a known good carb, you will know to look elsewhere for the problem. In a pinch, any Ford V8 carb back to the thirties will work for a test.
 
Final results; I found the two outboard carburetors were sucking air. Even though I thought I had to throttle shafts completely closed
They weren't seated all the way allowing a vacuum to develop. I sent them off to get new throttle shafts. No more running with the choke halfway closed! Problem solved! Hopefully this will help one of you guys out ,if you run into this problem. Thanks for all the replies....
 
Glad you found the problem and let us know. Now let us know how it runs when , you get the carbs back and the car running again.
 
Always good to hear from you Jim! Oh it's running, and with the y-block I rebuilt and the car is working properly. It's kind of scary fast for me.
 
Good to hear from you sal!
Just letting you guys know,I'm going to be having a couple of Ford 94 carburetors that I'm rebuilding for sale. one is an 8B. The other is a 7rt. They will have new kits installed from vintage speed. They will be pretty much stock. So if you guys know anybody looking for one of these carbs let me know..
