No "static" mark other than the line on the rim of the dizzy for the rotor to point at. Have no idea what the advance is at idle

Your impeller will have a TDC mark ... whether it is a hash mark or a zero stamped into it. I haven't seen one that was not marked with a TDC mark.


7.5 degree mark is for the 1.8 at idle (14.6mm to the right of TDC facing the fan).

27 degree mark for the 1.7/2.0 at 3000 RPM (52.5 mm to the right of TDC facing the fan).
