Ford 4300 Carburetor Rebuild and Choke Setup Episode 372 Autorestomod 

Hey Jeff - you're probably aware of this by now - but when you wondered why John peened over the top of the float needle. Apparently, this is one of the versions. Per copy on Mikes carburetor for part# NS561: "There is more than one style needle and seat assembly used in these carburetors, match your existing assembly to the part photo to be sure you're ordering the correct one. The other style typically used is a one piece assembly." Anyway, I love your channel. It's the first place I look for so many things related to my 351C '70 Cougar Eliminator...from suspension to drum brake conversion and Pertronix...to the 4300 carb rebuild!! Thanks !! Your first video helped me break the carb down, and I'm putting it back together with this one...after I get my secondary bypass plug from Mikes carb parts!!

Best show on the web.

Just want to say this video is helping a lot! I've got the 4350 for my Ford 460. It's confusing, especially since this is my first time working on a carb! But so far everything's been super similar between the two, so at least I had a base to go on

BTW...... That "Cap" you referred to, in front under the Float... Is a Ford retrofit Plug, that used to be a Secondary Enrichment Valve. The Valve, only fitted to 4400s and 4400Ds, was causing an overrich condition when the Secondaries were opened. It was found that on anything but the 429SCJ and 460 Engines - any Valve was too rich! The Plug improved Driveability. I'm a Retired Ford Tech and Engine Builder. Also an ASE Master Tech in Carburetor Tuning and Overhaul, EFI, Ignition, Suspension and Driveability.... Nobody will let me Host a Show, so I like to expunge Knowledge whenever I can. 😉

Zep Super Degreaser works really good for cleaning the carb. Better than simple green.

I just sold one of these. Good job on the video. Also, I liked your articles when you were with Mustangs Monthly.

If you need that spring for the power valve, check with Mikes Carburetor Parts Also has the new floats.

2nd!!! I was almost first this time. Jeff try vinegar to clean it up. I’ve used it on carbs for a while now.

Soda blast seems to work. Spray with the newer blaster surface shield to protect the surface.

Thanks for sharing this video, priseless when i rebuild my 4300 :-)

What's a carburetor do? haha Nice job with the vid! -Glen

Holy Cow Batman, the 4300 is OEM on my 72 LTD and this is NASA science stuff. I’m not sure if I want to make this carburetor renewal to keep my car stock.

First! And btw I love your guys videos. How's the Fairlane doing.

Does that air damper rod and piston go all the way to bottom of its cylinder ? Mine was seized up, used Kroil penetrating oil and got it freed. Now it will not go to the bottom ,gets stuck, any ideas on how to resolve this issue, I can’t find anything ?

My jets are stamped 367 and I have no idea what that means. They definitely aren't 3.67mm and are too small for .067. Does anyone have an idea? It ran okay but it was leaking gas so I'm putting in new gaskets.

Can you point me in the direction for my 2150 Motorcraft 2bbl for where the vacuum lines go and my 302 engine. Thank you and love this show

Hogwash used to work great! But it's not on the market anymore.

Thank you for an excellent video, both my AMC 4300s have the spring on the "bottom" of the secondary choke opening rod. I have always known them to be on the bottom. Is it possible the bottom is correct. This is the plunger on the left hand side of the carburetor..thank you

How did the 65’s work for you

Here at 15:40. Just how will this pin or shaft stay there??

Anyone know where i can get a backward screw that goes into the throttle shaft like the one he mentioned in this video.
