1964 Valiant "Get Runnin & Drivin"

Took old Vixen to town and back today and I have to say I'm impressed at what the bigger secondary jets did. Now all it does is just pull stronger and stronger. I can't "feel" the secondaries open, but you dang sure know when they do.
Is the carb setup with one Pv or two?
If only one of in primary, should not need more than 9 sizes bigger in the secondary.
What's the spread pri/sec?
