I'm just about ready to join the "Junk the Rochester" club! I've never been able to get one rebuilt right yet. I've spent the last couple of days searching all the threads and watching all the videos, and they've been a big help. I'm hoping that a bolter can clear something up for me, regarding the accelerator pump. I've installed the new pump and when pumped it fills the discharge well, and assuming it goes from there into the "chamber" right next to it? Again assuming from there fuel travels up into the air horn. Assuming there is a plugged passage from the discharge well, and soaking is the only way to clean it up? Please help. If needed I'm working on Rochester B off a 53 235.
