Timing light beginner- Help

[Indiana_Red@hotmail.com (Ken B)]

I am trying to check my timing on my stock Scirocco 16v motor.  I have a
decent light that has the "inductive" clamp that goes on the center dizzy
wire. Pretty simple setup really.  Whne I lean on the drivers fender and
shoot down and across under the intake boot I can see 2 marks.  One is
pretty much centered and the other is just barely in view about  a
quarter-half inch away toward the front of the car.  At Idle that is.  As I
speed up the engine, conservatively, that first mark slides on back as the
next one in front comes into center view and as I keep increasing it to
keeps moving untill it is out of view to the "rear"  All this before I reach
~3000 rpm.  Is this about right?   Bently says that the "mark' (6<TDC should
be lined up.  That looks right but I didnt expect it to advance that much.
Anyone elses experiance similar?   Ive never seen one b4

Thanks as allways.
