Initial timing is also called static timing. It's advanced.
Recurving means limiting the timing in your dizzy so you can use more initial timing. Some dizzies are set up with lots of mechanical advance. In this case you can't run too much initial without pinging. You want to run around 36* total with 12-14* initial. You want 22-24 degrees in the dizzy.
You'll need to find tdc on #1 on compression stroke and install a timing tab and acquire a good timing light to see where your timing is set at.
I'll search for a pic for you of recurving a dizzy.
