A guy set me a ringed Webra that he had got the ring gap caught in the exhaust port. I got a hold of the end of the ring and pulled it off the piston through the exhaust port like I was pulling out a piece of bailing wire. I thought the ring was heat damaged? Maybe it always was like the one in the video?

But I've put them on and taken them off like he shows in the video for 50 years.
