Timing light gives two different readings
Ok, here's the scenario:
If I set the timing advance on the timing light to zero, I read 15 degrees advance (pointer aligns slightly before the red mark)
If I set the timing advance to 15 on the timing light, it doesn't quite line up with the white TDC mark. Setting the timing advance to 17 on the timing light makes the TDC mark line up.
So which is the correct reading? 15 or 17? Has anyone else had this problem?

Re: Timing light gives two different readings (Luserkid)
Yes, I'm using a jumper to keep the timing steady at about 850rpm according to my VAFC.
It's a summit racing timing light. I guess I could try to find someone else with a timing light and compare readings.
