“My 1931 Ford was timed…”

My 1931 Ford was timed and the carburetor set to perfection in accordance with the original ’31 Ford maintenance bulletin. When I added the Howes Fuel Enhancer the performance and smooth operation was very SIGNIFICANT! Without exaggeration, I was immediately very, very excited with the increased power and the quickness of each starting of the engine.
