How to fix a Craftsman Sears 900 Tiller that will not start?

If your Craftsman Tiller won't start, there are several potential causes. First, ensure that the fuel tank is filled with gasoline. If the engine is not choked properly, refer to the “TO START ENGINE” section in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other possible causes include a dirty air cleaner (clean or replace it), water in the fuel (drain and refill with fresh gasoline), a clogged fuel tank (remove and clean it), a loose spark plug wire (ensure it's properly seated), a bad spark plug or improper gap (replace or adjust it), a misadjusted carburetor (adjust as needed), or a closed fuel shut-off valve (open the valve).
