stock main jet size 1967 650 65 hp

Does someone have a chart to see what the stock main jet size is for a 1967 Mercury 650 4 cylinder? My service manual skips that particular year and size in the chart it provides. Engine serial number is 2207126.

They go from .73 to.71 to .69 with .71 being standard.
