  Your Kohler Engine might start but not keep running due to several reasons. A common cause is poor fuel quality, so try using fresh fuel. Other potential problems include a faulty carburetor (repair or replace it), a faulty cylinder head gasket (repair or replace it), or a fuel pump malfunction (repair or replace the fuel pump and check the vacuum hose). Also, check for intake system leaks and repair them if necessary.

How to fix Kohler Courage Engine that cranks but won't start?
- D
  Dr. Rebecca Rodriguez MDAug 11, 2025
  If your Kohler Engine cranks but doesn't start, there are several potential causes. First, ensure the key switch or kill switch is in the ON position. Check for simple issues like an empty fuel tank (refill if needed), a closed fuel shut-off valve (open it), or low oil level (add oil). Inspect the spark plug lead(s) and reconnect if disconnected. Other potential issues include a blown fuse (replace it), a backwards battery connection (check connections), or poor fuel quality (use fresh fuel).
