Instead of using old innertubes to insulate and enlarge the tube for mounting, I used a piece of old radiator tubing. The rubber is better quality and much thicker. I noticed that when I would tape up the innertube, the gas that would leak out of the carb wolud mess em up and the would fail. My back mount did this and was loose and caused my frame to crack by the front mount. When I fixed the mount with radiator hose, the frame broke completely. Now I'm trying to find a new frame. I found an old western flyer on craigslist that has the headlight/tank on it. But the guy doesn't answer me.
