Almost like someone has drilled out the seat in an attempt to allow more fuel to flow into the bowl. You might want to check the seat isn't damaged - although you are getting a new set anyway but that could have been part of the issue.
[emoji2] I think I can answer that. This needle/seat set is stamped 3.3 on the bottom. I believe that's the orifice opening. When I went looking for a replacement set, I found them listed at anywhere from 1.5 up to 3.5, so the opening on this set is quite large, relatively speaking. Much like Jeffco's pie hole... not the biggest, but certainly getting there.
