WTF Big issue

Still looking for my Piston bump stop :BangHead: But I set my balancer at 10' BTDC popped the cap and took a few pics. Still don't see anything wrong. I still need to drain out old gas and refresh. White mark on outer dizzy is #1 cylinder on cap.

10* BTDC is not enough initial timing
I would start at 16-18* and perhaps go up from there.
Good luck
