Franks piston rings worked great for us. My friend bought a few Webra 1.20 engines, new. They use the dykes type of ring. One of his engines never did develop the compression the others did. We installed one of Franks rings and wow did it make a big difference. It had more compression even before we started it. That engine will hand start now real good, and has very good power. How many Webras 1.20 engine will hand start good??? If you know how to tune a engine right....you will have less problems with rings in the first place...just a general observation! Capt,n
