I would think only one pawl would lock into the hack-sawed line at a time Norm but must be enough to stop the starter slipping.
A couple of points we didn't mention is the pawl holder can't be installed upside down because the pawls will not engage with the cup because of the 2 flat edges on the pawl holder, they keep the pawls straight when they engage with the cup.
The pawls can't be reversed ,the hole in the pawl is off centre in the vertical direction. If you tried installing them backwards the friction washer would not be in contact with the centre of the pawl holder on one side.
