I know there's not alot of people like the PD carbs as they are fiddly to work with but they did work well originally in my experience, I also think they are definitely the right philosophy in that they run under constant load with a leaner mix and just richen for the acceleration demand. Means you get less fuel unburnt to contaminate the oil along with probably less bore wear.
This is after all what weber twin chokes on cars do and the American pumper carbs on older V8s which nobody complains about.

Compared to PD carbs, the old Holley's on my mustang many years ago were great, you could probably use a broom handle to clean jets, and the accelerator pump could probably pump the titanic out to refloat it in about 10 pumps!

One of life's great pleasures, sitting behind a nice V8 with the throttle wide open.
I've never owned a big yank V8 but spent alot of time with rovers and currently have a 3.9 on injection in a old Range Rover.

Hi Mark
I have been fiddling with my carbs for while & used plenty of carb cleaner as you , but I have not had any leakage of any kind from the very small hole that you are asking about. on my carbs that small hole looks like its sealed.
