Re: Opinions please - Quadrajet carb flooding
Get a rebuild kit so you have that top gasket and a new needle/seat. That is likely what it is, OR your fuel pump all of a sudden decided to shoot 8+PSI at the Qjet, which it cant handle.
The only issue with disassembly are all those linkages and having to "lift an turn" the top of carb off to remove.
Maybe someone near you in CA can help out, but if not, there are a-plenty of Qjet gurus here that can guide you thru the process using this BB. ( I aint one).
In the mean, I'd get the numbers of the carb ( usually in rear, stamped vertically ) to order the right rebuild kit. Pop the carb off the engine, set up a workspace where gas fumes aint in the kitchen, and start disassembly.
As we suspect the issue is the needle and seat. In the pic below, if you follow the arms of the float up to the casting, its all that stuff under the odd looking C clip.
