Igave up on finding a piston for my Webra 32. The carb fit my MDS 25 and it now idles and transitions really well. So Iguess I will sell off the rest of the Webra on that famous auction place.

One last possibility.

I wonder if a Magnum 36 piston and Liner set would drop in?

Idont know if Magnum ripped off er ah,,,copied,,,, uh ,, designed its engines in a similar manner to Webras.
