How to fix a Craftsman 850 that will not start?

  Sandra BennettAug 16, 2025
  If your Craftsman Tiller won't start, there are several potential causes. First, make sure you have fuel in the tank and that the fuel shut-off valve is open. 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 potential issues 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 (reseat it), a bad spark plug (replace or adjust the gap), or a carburetor that needs adjustment.

  If your Craftsman Tiller is hard to start, ensure the throttle control is in the 'FAST' position. A dirty air cleaner can cause starting issues, so clean or replace the air cleaner cartridge. Inspect the spark plug; replace it or adjust the gap if needed. Stale or dirty fuel can also be a culprit; drain the fuel tank and refill with fresh gasoline. Also, make sure the spark plug wire is properly connected. Finally, the carburetor may need adjustment.

  Andre WilliamsAug 26, 2025
  If your Craftsman Tiller engine overheats, start by checking the oil level and changing the oil if it's low or dirty. Clean the engine air screen and the engine itself, paying attention to the cylinder fins, air screen, and muffler area. A partially plugged muffler can also cause overheating, so remove and clean it. Finally, ensure the carburetor is properly adjusted.

Why does my Craftsman 850 Tiller shut off when engaging the drive control bar?
- E
  Eric HowardSep 12, 2025
  If your Craftsman Tiller shuts off when the drive control bar is engaged, it could be due to the shift lever being set between counter rotating till positions. Shift to either the counter rotating till position or the forward rotating till position. Also, check the tines and clear them if they are jammed.
