Sticking fuel valve
I tried this back in August without any responses so I thought I would resurrect it once more in hopes someone can help. I have an Andair FS 20 valve with left and right at 45 degrees, off facing aft. It is getting very difficult to switch between tanks. While everything was apart with the panel upgrade, I cleaned what I could without taking apart the valve itself. Has anyone has a similar problem with the Andair valve sticking? Are there user serviceable parts inside? So far, Andair hasn't been much help other than to suggest sending it to them.
