Yes unless you can make your own, you have no chance of getting it off without it and you'll probably break/distort the flywheel or hurt yourself trying any other puller.
I had the stator fail on one of these before. If you have a black stator it's not a question of If but when it'll fail. You should ensure you get the Red Stator and don't bother buying a used black one.
I've also seen all the magnets come unstuck from inside the flywheel on one of these engines where the harmless looking plug on top of the flywheel cowl was missing and rain water had got in and rusted the flywheel just a little. You'd tend to notice it though when you spun the starter! But check they're secure when you have the flywheel off.
