Topic: Need help on timing a K1, two problems...

[Texwing]

My back from the grave 1971 cb750 is doing great, but i ran into two problems tonight while timing and would appreciate ideas.  The first problem is timing marks-now i have a factory manual, the owners manual (but not the right one) and a Clymer manual,  and all three show  two vertical marks between the T and F mark, and also show the cylinders 1-4 or 2-3 numbers below the F mark. When timing, all books say to line up the mark to the left of the F mark, as opposed to the second mark right of T

The problem is my marks dont jive with the books-when rotating the crank, you first see 1-4 at the same level, and only one vertical mark between T and F, thus raising the question of why is mine different and what I am supposed to line up to static time?

The second problem is that my big points plate runs out of adjustment before i can get  to the the single mark between T and F 1-4.  I have read a tech post on this problem but darn if I can figure out what it is trying to tell me.  Any other ideas or points to other posts on the subjects would be appreciated.  I do well with pictures.

Thanks in advance!

"F" is the fire, points should open on the "F" mark,I usualy use 12v globe and alligator clips on earth and pos wire to the points, when the points open the light will come on, if you have no more ajustment the points rubbing block is worn down(the part of the points running on the cam) hope it helps.The "T" is for the cam timing,dont worry unless you've had the head off.sorry forgot to say ign. must be on to do this.
