is there i burr on the hole ? you could use to ream ? but not really made to back out and a off size i would use a drum sander on a die grinder (at low speed)you are at the center line of the crank there is no way you will throw off the balance of the engine try not to make it bigger then it has to so the stall has some way to center up would be better to turn down the stall on a mill or lathe you could use a small brake hone but will take a long time the grit is to fine .sunnen makes hones to do what you need but to buy all the stuff to run the sunnen hone it would be about the same price to pull it down and turn the hub hole out on a lathe
