  1. How can i identify the cfm rating of a ford
    4300 with out the tag.
    It seems( not 100% sure ) original to the car 1970 torino 351 cleveland 4bbl quench heads

  2. HAVE A 4300 CARB, WHEN REMOVING TOP OFF CARB NOTE THE POWER PLUNGER WAS OUT OF POSITION AND THERE WAS THIS LITTLE PORTED TUBE, MEAN SMALL THE SIZE OF PENCIL LEAD IN BOTTOM OF BOWL. DONT KNOW WHERE IT COME FROM. CAN YOU HELP ME OUT?

  3. I have rebuilt a Motorcraft 4300 carburetor and have a problem with gas squirting out of vent hole instead of squirting out the discharge tubes. I could not find a place to install the pump air bleed valves and since this is a 1971 carb I shouldn’t need one. This carb did not have a normal pump needle discharge valve but a ball bearing. I installed a normal discharge needle. To make matters worse, there isnt any carb identification numbers. Could you advise.?

    • The kits have a choice of air horn gaskets and you must use the correct one (see info sheet in kit to pick the right gasket}. The early “4300’s” use a small check ball to prevent pump drain back. The base # is stamped on one of throttle body ears. They only stamp 3 or4 letters out of a possible 5 or6, but I have a book to untangle them. there was a service up date from Ford recommending to eliminate the secondary needle & seat to prevent flooding! They actually make a plug to replace the secondary needle & seat, but I remove the needle and solder it closed. Disregard the secondary setting, just make sure the secondary float tab clears the plug. FYI you can use the float from the “4350”, but set the float level @ 1″ and they work just fine.

  4. Hi, have a friend with a 68 ford t-bird 429 engine// has a autolite 4300 carb on it /this is not a carb i think is any good// would rather use a 4100 carb on it /4300 needs rebuild// will call for kit from u / not crazy about this carb/ think it is an emmisions carb and usually have problems with it// see u have some used one’s for 39.00 dollars// what is ur thought on these// thank you Billy

    • I don’t have a problem with any carburetor as long as they are rebuilt correctly. The 4300 is too technical for most occasional rebuilders and when they have problems with the carburetor, they blame the technology. I know people replace them with the 4100 at times, but then they have other issues because the 4100 doesn’t have all of the circuity the 4300 cars required for running.

      Anyhow as you can see I am not a fan of switching any carburetor. I’m not a purest but strongly believe, for a lot of reasons, that the carburetor engineered for any vehicle should be used.
