Motorcraft mixture screws.

Where would I be able to find mixture screws for a motorcraft carb on a 73 f100 302? I have one that is bent and need to replace it. Thanks.

To my knowledge no carb rebuild kits include the IMS's, you could easily grab a carb at the junk yard and use those.

No trucks that old with that kind of carb in the junkyards around my area. I have another motorcraft carb that came off a Bronco, the screws in it are longer.

You'll have to find a set off another carburetor, be it a junkyard (I realize there are none in your area) or eBay. Pony Carburetors might also sell them, but I think they just set a minimum order in place.

Why don't somebody still make them when there are so many of these carbs still around?

Numberdummy im gonna call one of the guys you listed. What do you think two of them will cost? The tag on the carb says D3TF NA. Below that it says A 3E 7. I want to make sure I get the right mixture screws.

The demand is slim and none because these carbs haven't been used in 35 years (since 1974).

Two of the three sources I listed have toll free numbers, so it's a free call to find out how much.

D3TF-NA = D4TZ9510AV .. 2V Carburetor (Motorcraft CA1792)
