That is sort of how pull start pawls work. You need a rapid pull to swing the pawls out

A common mistake is to lubricate parts that should not be lubricated.----Friction is used to swing out pawls on most starters.

Just a post comment, centrifugal force is what swings the pawls out and as you realized, if the resistance to moving is lowered, they will sling out easier and work better and the faster you pull the rope the more energy transferred to the pawls to swing out.

On some motors it is friction that swings the pawl out.----On those greasing the bits is a mistake.

Well as you say, I never saw such and it defies the laws of physics if you ask me. If friction forces it out.....does friction put it back????? What is the mechanism that tells it that it's time go go back into hiding?

Time for you to look at some simple recoils I think.-----Say a 1979 model 6 HP Johnson.----Or a 1975 model 25 HP Evinrude.----Plus many other examples.----This is why some folks struggle , they do not understand simple stuff.----I struggle with a TV remote control.-----Not with simple mechanical stuff.

I had a 8HP Chrysler. It had a manual starter pinion gear that popped up when the rope was pulled out. When it needed grease, it would not engage the flywheel unless I pulled the cord rapidly out for an inch or two. It needed to be greased once a year.
