Alright so I got a couple of questions did I plug up the PCV valve to the carb correctly....i also sprayed some carb cleaner onto around them to check if i had vacuum leaks and it seems good....also was also wondering what is that solenoid next to me throttle cables do exactly?

and for some reason I am getting bad throttle response at idle....like wheni rev it it hesitates and goes up slowly...what could that be? ive messed with the idle mixture screws and have plugged up pretty much all of the vacuum leaks it had.

I am really close to junking this carb and buying an edelbrock carburetor....have been having so many problems with it.
