hesitation when excellerating

[RShaips]

Just bought another truck(last thing I needed!),1986 K10 LB.One owner 110,000 miles.auto,air, tilt and criuse, almost rust free , hard to find around here ! Anyway its real slow. When you floor it its like it almost dies then finally and slowly it will build up rpms and run. I am sure it need the carb overhauled. Anything else to look for ? Also one door is hard to shut,how do I adjust these , They are not like my 67 Thanks
