If you grounded voes per the sheet and hit 1500 rpms on curve 2 you should be at 34. If that is your ifnition, I believe it is. What John said is right I think you just set static on them then you should be dead nuts on the timing. Id check static first make sure your exactly at TDC when you do it and of course check your switch first if you're on 3 you're dead on already

So you're good you're dynamic timing check matched what it should be. Flip that to 2 or 1 and see how you like it. No need to use the timing light again.

I did when I checked to see what it was at. Not really sure how it all worksbut after switching it to 2 it seemed to have a bit more go.

I'd start with curve 1 and if you get any pinging switch to 2. Unless you're lugging it loaded down 1 should be fine. If you're happy with 2 though let it be and ride.

So is the whole idea of the curves for pinging or am I reading this wrong?

Start at one and if you get pinging go to two if it persists go to three if is still pinging in four you have other problems.

FWIW, my Twin Tec 1007 ignition uses higher numbers for more aggressive curves. Thought I'd throw that in so future readers would know that it's different from module to module.
