4350 Rebuild - Ristow

puttin' a carb together for a pal. thought someone may find it helpful if i showed my work.

4350 motorcraft off a FSJ.

first,remove the top cover screws. 10 of them. they are the larger phillips headed screws. i forgot to snap a pic of the float removal,but pretty simple.pull the pin.



next,remove the clip from the accelerator pump link,at the throttle arm.



there is also a clip on the lower choke link,remove it,to remove the link from the lower arm.



and the top will lift off. this is the underside-what's inside the carb.



here is the main body with the top off.



next,remove the 6 screws holding the throttle body to the bottom of the main body.



and separate them.




next,we'll move to internal dis-assembly.

on the internals,first we'll remove the brass plug,shown here near it's bore,it falls out.note there was a small steel ball next to it,look in the above pic,in the main dis-assembly part,and you'll see it.



next we gently pry the plastic retainer for the needle assy. out to release the needles.





next,the main jets,and needle plunger tube.i used a putty knife as a screwdriver on the tube,it's pretty wide.



accelerator pump ball retainer and check ball...



this is optional to remove.



next...top cover.

Nice job. Have a couple of questions/additions:

Did you find that one of the screws was longer than the rest? When I did mine recently one was longer and it had a regular slot screw head. The instructions with the kit I used indicated that one should be longer (but the same instructions had an incorrect number of screws.)

I think it's an extra inlet needle and seat - supplies extra fuel under certain situations if I recall correctly.

How necessary is it to remove this? Is it because you dunked it in the carb cleaner? Didn't remove that on mine and wondering if I missed something important.

The service manual advises to use caution removing and installing that tube as it is easily damaged. When tapping it out/in having a support rod in the middle of the tube will help keep it from collapsing.

Looking forward to seeing the assembly process - be interesting to find out what I screwed up in assembling mine (it's still not quite "right")...

Thanks

I wish you would have posted this about 4 days ago. I've can already tell I did something wrong.

Do you think if the springs on the Accelarator Pump and Secondary Plunger are switch if it will create a problem? I know one is much beefer than the other.

yes,it is a problem. it will give you a weak pump shot on the accelerator pump,and cause your air door on the secondaries to open very late.


mathman,
yes,one longer screw. on that vent,i removed for the carb dip solution. i think i will blank that fitting off,as this carb will be used in a non-emissions application.

Exclamation Warpage?

Did you detect any warpage between the upper and bottom halves of the carb once apart?

I have a 4350 to install to my 401, and a search of the 4350 on this site revealed that many have had a problem with the pieces being warped after they were separated. In other words, the carb ran fine but needed a rebuild due to age, and after the rebuild the carburetor was warped and did not perform well with the kind of leakage the warping introduced. Several seemed to have this specific problem.
