Based on the replies, I'm going to share where I got this idea. I might have got the wrong impression or maybe that is what he meant.
I was personally taught in auto school to replace rings, nobody never even suggested such a thing except this video. my engine hardly has any ridge and ran before taken apart but is an original 74 engine that was taken apart for other issues and is intended to be overhauled stock.
What shocker:rolleyes:
I bet he told ya to use butt grease to assemble it with and some ashes down the carb for good luck. Ring like any other metal alloy have a fatigue life imo getting them hot like in an operating engine..then bending them out to remove and worse.. leaving them on then honing it .005-.001 larger...they've lost their spring so to speak...if there was out of round..the ring is out of round after it's been broke in..
Its a great "watch this"... or.. "I cant believe it worked, or runs"... but that's shoe laces for a belt, bubble gum for glue. Its lame.
