What are Torque settings for intake manifold cap nuts on a 1985 Honda BF75.100

[guideken]

I have pretty much rebuild the innards of my Honda BF75.100 motor with just this last thing to do. Does anyone know the torque settings for the intake manifold cap nuts on a 1985 Honda BF75.100 motor? Would really appreciate help with this since i dont have a repair or maintenance manual

Honda Standard torque value for a 6mm flanged nut is 9ft-lb or 12N-m.
