'82 is a CCC, or computer controlled carb. Difficult for an expert, impossible for a rookie. First take a few pictures of it from all angles for reference. Then take off the gas line with a 5/8" flare fitting wrench, while holding the big 1" filter housing nut with an open end or adjustable wrench. It is easiest while the carb is still bolted on. Then remove the throttle cable (don't lose the clip!), transmission cable, vacuum hoses, and all wiring carefully without breaking anything. The grey choke wire clip breaks just by looking at it. Once stripped down of attachments, you can remove those four 1/2" bolts, and take it off. Now find someone who knows what they are doing and have it rebuilt properly. No parts store generic rebuilds! Keep that original carb!!!!
