Not being a smarty, but try a ring compressor.

Yea, I always have used a ring compressor. It's a relatively inexpensive tool.

In a pinch I have gotten by using a hose clamp.

This is a one time operation so I may give the hose clamp a shot first.

The old MacGyver tool is a soup can with ends cut out and slit up the side plus the hose clamp.

Measure it with a micrometer; cut it with an ax.

Over the years, I have installed hundreds of small two stroke piston in chainsaws, blowers and other.
I have never used a ring compressor.
I install--CAREFULLY-- with fingers and occasionally add the aid of a popsicle stick.
I had a friend break a piston ring trying to use a worm clamp and finally used a wide plastic cable tie after purchasing another set of rings.
There are many special ring compressors available as a set.
