Topic: Autolite 4300 ? update

[Wills70]

I have a C9ZF-C carburetor that is missing a spring, it is attached to the accelerator pump lever rod and dash pot bracket. Can someone please help me with a part number or where to find one?
Thanks Will

This is an excellent task for you to use the "Ford Car Parts" (aka MPC) section in the library.
First, locate the Ford part number for the carburetor in the text section, then look at the Illustrations of that model to to determine the Ford base number for the spring, then back to the text to get a Ford part number for the spring. This is what I, or anybody else would have to do.

When I clicked the link in the library for 1970 Mustang Article list, it went to the Thunderbird website we have used (with their permission) to get access to 1965-72 Ford Car Parts (aka MPC - Master Parts Catalog). Your drawing information is in file "09-1965Illust-FuelSystems.pdf".

Think you may have to get one from a donor carb. May be able to widen your search to include carbs from other years to improve your chances

Some examples


68 NOS examples




69 restored example




70 original examples

Thanks Jeff , while i was in the library i was looking at different years and models for the same spring being used - nothing found yet. This spring has a 1967 part number being used on a 1969 carburetor so one would tend to think this was used before elsewhere ?
I have call in to West Coast Cougar and a Wanted add for a possible used part - also a carburetor shop I contacted said they would have one that would work , so all is not lost
I'm sure thousands of these springs were made and I'm willing to bet there is still one out there laying around somewhere ? Now armed with a part number will aid in my search 
And a big Thanks to you Jeff for all your hard work in putting the library together - very valuable tool!

A reality check meant in a helpful way is in order . Part numbers are important to know. With that said  knowing the part number is down the helpful list compared to a picture with length and diameter measurements (for a spring)when looking for a used part IMO. The vast majority of people who sell used parts do not typically have a part like this categorized with a part number. It is most typical for people who sell used parts to rely on application and category of usage on a given application . A part number is for secondary confirmation if at all depending on the part. Rattling off a part number is the quickest way to get a used parts vendor eyes to glaze over and just say they don't have a small obscure low value part. I would first ask if they had the carb spring for the application, type of carb and its location on the carb . I would offer the measurements and or a picture for the spring in question to confirm its identity. Offering the part number would be in the "if all else fails" category in this case for a used carb spring IMO. At least as it pertains to a low value used parts.

Did you call Jarrod at allcarbs.com, this is in his wheelhouse and what Bob Gaines recommended might be all you need to ask Jarrod.  He is rebuilding my 70 autolite right now.  One year/model only and he comes recommended by drew podjednic. 

Hope he can help you.

Update on my findings, with a known part number I searched the catalog for a carburetor that used the same spring, 429 / 460  4V carburetor matched, and gave me the dimensions of the spring that was not given under the 351W part listing. I noticed a FoMoCo carburetor kit that contained a spring that appeared to be correct - measures to specifications. So an NOS spring for my 1969 Shelby GT350 4 speed Autolite 4300  4V carburetor.

    Thanks again Jim - for sending me to the library!
        You made my day!

Giving you the answer would have solved your problem. Showing you how to find the answer and how to use other resources available, puts you at the head of the class.
