1968 Briggs & Stratton emitted black smoke and would not draw fuel below 1/2 tank.

Removed fuel tank / carb assy, then separated carb from tank. Replaced diaphragm, and both fuel tubes. Also diaphragm spring. Engine now starts and runs well. Draws fuel all the way to the bottom of the tank until empty.

Runs like new again.

The parts I requested all showed up and were as good as I had hoped they would be. Now the more runs like it's new again.

Exact part, but also came with new carburetor.

If you need this seal and are buying a new carburetor, it comes with one. So now I have an extra one.
