Hello all,

Im wanting to rebuild my 2 barrel carburetor on my 1970 mustang coupe with a 302-2V. I'm having trouble identifying the carb. On the carb it says it's a motor craft and it looks like the original. But I'm not sure if it's an Autolite 2100 or a Motorcrafr 2150 carb. Do the rebuild kits need to be specific towards each one?

Thank you any help would be greatly appreciated!

Autolite was the original "Ford brand" for parts (other than Rotunda, which has just been for service tools and equipment for dealerships for decades now). Motorcraft replaced Autolite as Ford's brand in the late 60s or early 70s.
On 2100s, the difference between Motorcraft and Autolite is the name. Between 2100s and 2150s, the difference is a variable air bleed system on the 2150 to keep the air/fuel ratio dialed in better for performance and emissions. 1983 and newer 2150s were computer controlled.

http://www.mustangtek.com/2100/ford2100.html Here's a pretty good ID chart on most of the 2100s.
http://www.carburetion.com/ford2v.htm Comparison of 2100 and 2150 side-by-side and parts.

If you can find the part number on the carburetor, and then find a parts store that still has an old GP Sorensen, Holley, or Motorcraft paper catalog to decode those numbers, they can get you the right kit for the job.
