Hi, the 2 mark on 20B shaft pulley is 0° for Leading and 0° for trailing, or the first mark i see (left) is 5° ATDC for Leading and the second is 20° ATDC for trailing?
Microtech recommend put 5°ATDC, is with Leading or Trealing side?
Thanks

 

5-degrees ATDC is the right side mark, and it's for the front leading.
