When static timing, points "open" at F mark correct?

May or may not be a silly question to ask.

You're not answering my questions.  :-\  At what RPM are you setting your idle with a gun?  Is there preload on your advancer springs at idle or at rest? If you're springs are stretched, which happens when they get old, you can lose up to 10 degrees or so of advance, which is 1/3 of your total advance.

So, with the timing light on and bike idling, this is where the points plate is when the F mark lines up with the index mark.



For reference, when I set static timing the hash mark on the points plate was pretty close to lining up with the mark on the head.

That's retarded not advanced.  As you move toward the timing mark (right) you're advancing it.

Right. If I said advanced that's my bad, it's retarded. I'm setting idle timing @ 1200 RPM.

Re-check static. Advancer is mechanically locked to the cam w a pin or key or something?  So, it cant slip on cam.

That's way too retarded on the timing.  If anything, you should be slightly on the other side of the mark.
