I cleaned the area around the stem an tilted the stem to open up the tear. I applied the glue into the crack and surrounding area and then placed a 3/8" round tube scrap over it and squeezed it for about 40 seconds. Finished out the ride and made it back home.

I am now going re-enforce all my tubes around the stem by taking a nickle size patch and punch a hole in the center and slide it over the valve stem and gluing it in place.
The tubes often seem delicate in the area around the stem. Outside of snake bite flats this is my second most common failure.
