That's an offshore-made copy of a Holley 2 barrel that was used on various sizes of Ford V8 engines in the 1960's and 70's. It's far too big for your application, and probably calibrated for an engine a few cubic inches bigger than a 292, so it's going to run lean. Expect a lean flat spot on acceleration and possibly backfiring unless you're very gentle on the gas pedal. To adjust the position of the choke plate, loosen (don't remove) the three screws that hold the sheet metal retainer over the black plastic cover and rotate the cover to change the spring tension on the linkage that operates the choke flap. The screw that goes into the plastic bell crank in your photo is used to change the position of the fast idle cam.
