Default L98 Timing marks...

can someone post a pic or just draw me the timing marks on a L98. I'm having a difficult time seeing the numbers on mine, but I can still make the lines out.
TIA

The edge of the timing marker looks like a series of V's. The bottom of the largest V is 0 or tdc. Each top and bottom from there is 2 degrees whether you go up the marker, (advanced) or down, (retarded).
Definitely not the best explanation but couldn't think of another way to put it.

What everyone else said is correct but the center of the deep 'V' or 0* is 4* from the first peaks in each direction. Then the smaller valleys are 2* in and 2* out.
Hope this makes sence.

Scrub the tab with some steel woool. The rust or whatever else that is making it hard to read will be left in the impressions for the numbers and lines and will stick out like a sore thumb then.
