If you want to know the timing specs then here it is 4 degrees before top dead center / BTDC. Top dead center is zero on the timing bracket / Tab.
BTDC. are the marks on the left side of the zero on the tab.
ATDC / After top dead center are the marks on the right side of the timing tab.
Hope this answered your question. If not please ask it again.
