timing adjustment.
Not Tracy, although sometimes I fool folks when I don't have
a mustach {:>)
However, I think I can answer your question,
Tommy.
What Tracy is saying is that he is playing with his timing
advance/retard. Normally if you set the static timing like Tracy says to
do in his instructions, you would have the plug firing at between 20-23
degrees Before Top Dead Center at any rpm greater that 3600 rpm. (Remember, Tracy's system only retards the timing, it does not
ADVANCE it. When you think you are advancing the ignition time what you
are really doing is dialing in LESS retard. That is why setting the
static timing per Tracy's instructions is important because what you are
really setting -is the maximum advance for the system through the physical
adjustment of the crank angle sensor. Then when you adjust the timing
you are backing off of that advance. In other words, your maximum
advance on the controller is actually the minimum Retard position)
However, if you do what Tracy mentions in the first, clipped part of
that sentence, then your timing above 3600 rpm would be closer to 20-23+5.625
or timing may range from 25.625 to 28.625 BTDC.

Tracy,
Would you further explain this
line?
".... The
timing is advanced by 5.625 degrees more than nominal timing which is
typically 20 - 23 deg BTDC at rpm > 3600. "
