    They're not, different jetting and idle settings for fuel economy and performace, each is properly tuned to their respective engine and cam. If you're having problems send it out to a professional for a proper rebuild.
    I dont recommend touching it yourself or slapping and aftermarket carb on to solve any problems.
    Qjets are very good carbs when properly maintained and GM designed the 307 in 86-90 to be the front runner of carburated engines for fuel economy and performance.
    Hence the roller cam and swirl port technology.
