There must be 100 special tools that are "required" to work on things I've

because
a manufacturer sells a tool for a job does not make that the "right way". And
just because you say it does not make it so either. If it does the job
without
damage and is quick and cheap - it's the right way. Especially if it avoids
having to order and pay, and wiat for a special tool.

I think part of this might well be a liability issue. B&S drills a
couple of holes in the flywheel, and then publishes instructions to tap
them and use a puller. That way, if someone is inept enough to screw up
the hammer whack, damaging either the motor or himself, the company can
readily deny any claim.
