Motorcraft 2100/2150 Theory of Operation

[content22207_2]

Taken from a 1970's AMC manual (AMC used Motorcraft carburetors). The carb pictured is an early 70's rendition with choke pulloff integrated into the top casting (this is the rendition I use for Peugeot conversions to maximize ignition distributor clearance -- Peugeot manifold offsets the carb to the rear). Later model 2100's and 2150's have choke pulloffs hanging off the back. 2150's have variable size air bleeds, to reduce idle emissions, via "baseball bat" shaped rods raised and lowered by a cam on the throttle plate shaft.

Virtually identical presentation is in 1970's Ford factory manuals, Volume 2, Pages 24-25-1 through 24-25-10.

Information also can be found all over the Internet (this site is pretty good, but certainly not the only one: http://www.351c.net/archive/tech/bub...2v-carburetor/)
