Depending on the degree of leakage at the throttle shaft, it might not be a big deal.
I’d guess that most/all Rochesters that have NOT had an intentional reaming/bushing job on the throttle shaft…..would fail the carb cleaner test. I strongly suspect my Carter YF would also fail that test.
If you can get it to idle down, run at a high and stable vacuum, and not puke fuel all over the engine….you probably have bigger fish to fry than a throttle shaft that isn’t factory tight.
