Distributor curve help needed

I left those two springs in there and bent the tabs in. I noticed that the two pegs that slide in and out of the crossmember are already 1/2 way in the slot. Strange?

Halfway on the long loop would be about half of the advance available. 8.5* crankshaft degrees
The primary spring should have enough tension to hold the weight at the bottom of the slot.
Otherwise you will find the timing changing with idle rpm.
