It seem to me there's always a question about valve removal in here.
I've searched the Tube and there's an old video of a guy removing valves with a long bar but not a detailed up close video.
Has anyone made such a video and posted it?
I have a set of those All-Power tools but they aren't easy to find in good condition these days but they are still out there. They work really well unless the old motors are very rusty.
