When I ran a small engine shop I would rather work on a B&S than anything.The Tecumseh was a piece of junk as far as I was concerned.The best small engine that they ever made was the Wisconsin.If you are going to use anything as a starting fluid, get a can of spray carbureator cleaner.Give it a shot in the carb, and if you have any fire its going to start.It sure saves allot of pulling and cussing.
