I am overhauling a DK4 automatic advance distributor. It seems to be in fair condition, apart from a cracked cap and worn serviceable parts. It has an 8 degree advance plate, but I understand that the version fitted to the higher compression engines has a 12 degree advance. As my engine has the later higher compression Ruby head, I assume that 12 degrees is more appropriate. Does anyone know how I can modify the base plate to give the extra advance? I assume that the holes need to be enlarged, but does anyone know by how much?
Regards,
Jamie.
