I'm so glad I asked.

I know that Bowman rings make a big difference over perfectly good stock rings.

He even made a set of rings for me that fit a Tamper.
That's a engine powered pogo stick with a big foot for compacting the earth.
It was so old parts were no longer available.
I sent him the cylinder and piston and he did the rest.

Frank; There was a discussion about your rings in a Stihl 066.
How would your rings compare to the stock rings?

Would they be able to with stand the large exhaust port?

As you know that is the trouble spot on most 2 stroke engines.
