a thought might be to determine where your true TDC is and then establish a mark accordingly.

This is sometimes done by drilling out a sparkplug and putting a rod down to contact #1 piston, and then slowly rotating the motor by hand.

Once that is established, then you can decide if you want to set your timing at idle, or at full advance.
