can anybody tell me what size this carb is so i can by a gasket set for it 2100 or 2300 ? i just have no idea how to tell what it is the tag reads 9da2 E 8L 9 AND CAN YOU TELL WHAT IT CAME OFF OF I WOULD APPREACITED IT VERY MUCH

There is no such carburetor ID number prefix of 9da2 or 9DA2. What you posted is all mixed up.

The prefix starts with a letter, then a number, then two additional letters.

Like this, for example: C9AF. Then there might be a basic number of 9510, followed by a one or two letter suffix. Examples: C9AF-9510-E or C9AF-EA.

8L could be: November (L) 1968 (8) or 1978 (8).

1963/74 Auto-Lite/Motorcraft 2100 series 2V carbs use the same carburetor kit. There is one variation. 1970/74's have a choke pull-off diaphragm mounted to the top of the airhorn.

All you see is an L shaped rod protruding from it. This diaphram comes in the kit, whether the carb has one, or not.

But...from this mixed up prefix you posted: 9DA2, this could actually be D9AE, there is no 9510, but there are 18 possible suffixes, some have three letters.

1975/79: There are 15 different 2V carb kits.

Has the engine been swapped to a 302 or 351W? 1979 LTD/Mercury Grand Marquis came with these two engines, the ID prefix used for both these cars is D9AE.

 

hey bill
im looking at this carb and the tag on the carb reads 9DA2 and directly under tha says E 8L 9 as far as what it came from i have no idea it was in a box in the tuck when i got it and was told it was on the 360 it is elec choke i belive the engene is a 1974 if that helps. thanx

 

AMC also used Motorcraft 2100/2150 carburetors for many years and they tagged them with a short 4 to 6 character code. "9DA2" matches the code for a Motorcraft 2100 or 2150 that was used on AMC and Jeep 304 engines from 1979-80. That particular carburetor has a 1.08-inch venturi, so the number 1.08 should be cast into the side of the bowl.

 

the only other number i can find is on the bottom of the bowl is a large 13. do you have any idea what size the jets should be for the 360

 

Maybe you should post some pictures to accurately identify the make/model carburetor you have. The Motorcraft 2100 has the venturi size cast into the driver's side of the bowl. The numbers are in the center of a circle, and they might not be too easy to read because the accelerator pump rod and idle solenoid may be in the way.

 

wife has the damm camrea. but i see the number in the casting and it says 1.08

 

Motorcraft 2100 and 2150 carbs with 1.08" venturis were used on the AMC 304 and Ford 302 engines. I think 360 engines used 1.21" venturis, but I could be mistaken.

Since that carburetor is probably jetted for a smaller engine than your 360, it will tend to run a bit richer when transplanted to a larger engine. Lots of 1.08" venturi carburetors came with #47 jets, but I think #46 jets are still available from places like Carbs Unlimited.

the jets in the carb are 47 so you think i need to use 46 or smaller, i dont know anything about carbs i thought larger jets for bigger engines so i need to go smaller is you advice , i really appreciat your help

 

The jet size totally depends on the elevation you are running it in. I have a 2100 and live at about 500 feet in elevation and I am jetted for sea level to 5000 feet in elevation. The correct jets for my 352 at this elevation is 52F. The 52F is a Ford jet and I have found the number is strictly a reference number and nothing to do with the size of the hole in the jet like you find on Holley jets. A Holly jet will not fit in the 2100 carbs. I might also say that if you look it up in the Ford parts mamual that not only elevation is a factor but also the type emission system you have and automatic transmission or manual transmission.

 

i live at 500 feet as well and is an automatic

 

I can't guarantee that smaller jets are what you'll end up needing. I just wanted you to know that you might need leaner jetting, and why. If you do need smaller jets, your options are limited since #46 seems to be the smallest available.

Carburetors for larger engines will usually have larger jets. You're right about that. Usually, though, the venturi size is also increased for more air delivery at the same time.

My advice is to just try the carburetor as it is now. It's an emissions era carburetor and is probably jetted on the lean side anyway.

 

Smaller venturies mean less air, less air in a bigger motor means more fuel which = richer. Higher elevation = less air which = richer. A bigger motor WILL require more air but not necessarily more fuel if you want it to run right. The smaller carb will probly work but you'll get horrible millage even thou its a 2bbl. I would think about a small 4bbl carb in the 550-600cfm range that will perform better and use less fuel.

As installed, if you look on the driver side front mounting ear on the surface facing the driver side you will see some codes stamped into the carbs base...this info is used to determine the carb ID...tags can be swapped around..but ya cant swap around something thats stamped in...let us know what ya have there...
