Timing marks on 1970 Mecrury 1150 inline 6

Hey all. Plz bear with me if this is stupid question. It seem to me that this sticker shows ATDC and I thought it was suppose to be BTDC. My 3 dots line up perfectly with spot on sticker that read TDC and all number are to the right of that mark. Also the 2 lower marks line up together but not with top 3 dots or that TDC spot on sticker. Im

Timing usually does not go out of adjustment on these.----What is your motor doing / not doing ?

You sound to me like another of those automotive guys trying to time an OB at idle!

Take the screw out of the top carbs throttle lever (so it can't move) and fire her up. Open the throttle wide open--only 3 grand or so--and time it with a light. Look for about 20-22 degrees of advance.
