  Kathleen JacksonAug 14, 2025
  Your Sears Tiller might not start for several reasons: it could be out of fuel, the engine might be flooded, the air cleaner could be dirty, there might be water in the fuel, the fuel tank could be clogged, the spark plug wire might be loose, the spark plug could be bad or have an improper gap, the carburetor might be out of adjustment, or the air filter is oil soaked. Try these solutions: Fill the fuel tank, wait a few minutes before restarting, clean or replace the air cleaner, drain the fuel tank and carburetor and refill with fresh gasoline, remove and clean the fuel tank, ensure the spark plug wire is properly seated, replace the spark plug or adjust the gap, make necessary carburetor adjustments, or replace the air filter.
