Avs2 650 tuning on a 340

I checked timing. Hopfully you can help me out if this sounds correct. Bumped engine till it pushed my finger off #1 spark plug hole. Moved balance to line up Mark's ( groove in blancer lined up to 0 on tab. Rotor is pointing just past #1 plug. Less than half way to #8
I don't have a piston stop to try it that way.
