Motorcraft Carburetor Rebuild

The Motorcraft 2100-D two-barrel carburetor was ubiquitous on Ford small-block V-8s throughout the Sixties. Appearing as early as 1957 in Ford and Mercury cars (including Edsels), the 2100-D later handled aspirational duties for (among others) Fairlanes, Mustangs, Meteors, Galaxies, Comets, Cougars, station wagons, and pickups. This two-barrel even made its way onto 1968-69 AMC 290- and 343cid engines.

Carburetor rebuilding can be intimidating. The sheer number of parts alone have been known to make grown men flee to a carb rebuilder. But with a little patience and some attention to detail, the job can be completed by anyone who possesses average mechanical ability and common sense in approximately one afternoon.

The 2100-D handled aspirational duties for Fairlanes, Mustangs, Meteors, Galaxies, Comets, Cougars, station wagons, and pickups.
The first order of business is to buy a rebuild kit for the Motorcraft 2100-D. These kits come with enough parts to cover many years' worth of variations in the carb, so rest assured that not all of the components will have to be implanted in your old unit. In addition to the kit's instructions, first-time rebuilders will want to refer to a service manual or even one of the specialized books devoted to this carburetor.


Overall, cleanliness and organization are the common denominators in a successful carb rebuild. Components should be cleaned thoroughly during the disassembly, then possibly set aside in the order they were taken off. Documenting the disassembly with a video camera or digital still camera can prove an invaluable reference when putting the carb back together.


The Steps shown here give an overview of the process (on a '66 Mustang) to help you decide if the job in within your skill level. The main motivator is that a rebuild kit is a lot less expensive than exchanging the carb for another or having a shop do the work. Your car or truck will thank you by no longer sputtering and stuttering.
