Erratic Timing
If you need to delay the start of the advance, put more initial tension on the primary spring.
One way to do this is rotate the spring perch on its eccentric.
When you have the distributor out, you can file a screwdriver into a tool to do this. Then in the future you don't have to disassemble the distributor to adjust the perches.
The other way to do this is welding a bead to the inside of the slot. Without a little more info, I'd be hesitant to do that just yet.
But if you're thinking around 32* is probably the maximum timing, and initial will be around 8* or 10*, that does seem to be the way this is heading. In other words 22 to 24 in the slots...
