OK, I understand the timing mark on the IP pump. I am still unsure about how to tell which stroke is the compression stroke.

I mean do I just turn the engine to 15 degrees and set the pump to the correct position with the locking pin? Or are the two 15 degrees positions? I do not want to set the pump out 180 degrees basically. I want to ensure that it is injecting on the compression stroke. So is there a way to tell when I am on the compression stroke or is that not important for the pump timing?

Also when I am looking at the flywheel from the top which direction is after TDC. Is it to the left or the right when looking form above? I know that these may be simple questions, but I have never timed an engine before and Just want to make sure I get it right.
