My home inspection of Speedmaster heads
Just to be clear we're talking about the end of the spring and slag, flash or burrs Its been mentioned elsewhere that the way the spring is cut/produced is the cause, they weren't cleaned/finished properly. I've seen springs that break because they were junk quality (um, yeah don't say it I've read it all!) never for what amounts to de-burring.That for me would be a see it to believe it.......again as relates to de-burring the cut. I'd be more concerned leaving the spring as is with the retainer pushing that end out.
