I wonder if I blew the rings somehow.

When I put my finger over the hole after removing the spark plug, and
pulled the starter cord, there was only a small puff. Noticeable. But

You can always try the compressed air trick. If it won't run
on compressed air, there could be an internal problem with
the piston and rings.
