Hi John P
The pulley rim is 108 mm (4 1/4 inches) in diameter and represents 720 engine degrees, so 10 degrees is 4.7 mm and 22 degrees is 10.4 mm.
I made a small filed notch mark with a tiny blob of white paint on either side for contrast
I set TDC by using a dial gauge clamped to the cylinder head with a rod down the spark plug hole. Best to set the TDC point midway between two points slightly either side of TDC
