Worked as advertised. No complaints thus far but only used it once.

I’ve got a couple of homemade tools that are minimal, so I decided to try it and see. The angle of pressure applied to the valve spring ensures that the spring remains level. Simple to use. I rarely need the tool but it’s worth every penny in simplify the process. Perfect.

I have not used the tool but bought it for my tool box and to share with others. I saw this tool used by a Mechanic on my plane for a push-rod tube gasket replacement on our Bonanza away from home base. Much Better than the screw driver and rocker cover screw routine many of us have used. Easy to use. It works! Wish I had invented it.

Doesnt seem to work with angle valve Lycomings unless I replace the bolt to press on the valve spring with a much longer one.
