Hi all! I have a weedeater lawnmower, with a 4.5 hp Briggs & Stratton engine, that was left out in the heavy rains AZ got last week. I have replaced the gas tank, air filter, and spark plug. Cleaned everything out as well as I could, gave it a shot with the air compressor, put in new gas. It's getting a spark, but I can't get even a hint that it wants to turn over. I don't know what else to do with it. Is it dead?? TIA for any help
