Hi to all
i have a question what is the BIG difference between FB rings to the original ones?
why peaple run to change there original ring?
why to open a brand new engine and replace the ring?
is FB rings made from gold or diamond?
i fly for many years gas engines without FB rings always use 32:1 synthetic oil for normal fly and for run-in i used 32:1 mineral oil for the first gallon
so far my engines are running like new,seriousness i can'tunderstand the logic behind this

Happy flying
