RE: Webra
Two of my fave engines are Webra .91s, one is an old ABN and the other an old ringed engine. About three years ago I bought a new piston, liner and ring set for the ringed engine. The ring never took a set so yesterday I installed a Frank bowman ring in the .91 and even unrun there is a huge difference. I also installed a FB ring in my ancient SuperTigre 4500.
