So I recently got a 260z last month and this problem has finally gotten to me. The infamous post emissions Flat top SUs are bogging when I lay the pedal to the metal. They will just begin to barf gasoline out the overflow valve if I start it up and rev it while the carbs are still cold. But this especially happens up in the hills (In Alaska) and no matter how slow I start up the carbs they will bog and puke up good gasoline. All I can do is floor it till what I assume is the floats go back up. Usually all it takes is flooring it till it touches off on 5k revs. But this problem is very persistant and when I come down from the hills after the carbs go cold all they wanna do is bog for the next 5 to 10 minutes. Now I'm just gonna guess this problem is from sticky floats and fouled up Emission carbs. (cept for all the emissions are taken off because Alaska)
