rebuild fuel selector valve

I have been studying the valve drawings and come to the same conclusion myself about either corrosion (most likely) or some grit stuck in the ball/seat area. Also, been doing some research and B&S in Wichita is on my call list.

I have one of the old valves on the shelf. I'll take some pictures so you can plan your attack.

sounds great. surely there must be a matching internal c clip somewhere (I've been shopping internal c clip assortments-a kit with various assorted sizes very affordable) or if part is serviceable, clean things up and reuse.

There is! It's this little self-destructing thing that springs itself out of position once removed.

I dug out the old fuel selector valve. I have no recollection of how to attach a picture so I'm attaching several pictures. My computer has a .020" diameter thumbnail of the picture which is useless. Unfortunately I don't know how to add any descriptions to the pictures.

Here is a picture of the o-ring that sits on the shaft of the selector lever. This could be a source of leakage.

oh my goodness. that internal clip that holds the spring does look like it will be a problem. I wonder if an internal c-clip would work in it's place.
