  Several factors can prevent your Craftsman Chainsaw engine from starting. It could be due to an empty fuel tank, which requires filling with properly-mixed fuel. If the primer bulb hasn't been pressed enough, press it 10 times or until fuel is visible. A flooded engine can also be the culprit; in this case, move the choke knob to Position 2, press the throttle lockout, squeeze the throttle control, and pull the starter rope. Old or improperly mixed fuel (over 30 days) necessitates draining the tank and adding fresh fuel. Finally, the spark plug might not be working properly, so refer to the section on maintaining the spark plug.

What to do if my Craftsman Chainsaw guide bar and saw chain are running hot and smoking?

  Melissa RiveraAug 21, 2025
  If the guide bar and saw chain of your Craftsman Chainsaw are running hot and smoking, several issues could be responsible. First, the saw chain tension might be too tight; in this case, adjust the saw chain tension. Also, the chain oil reservoir may be empty, so refill it. Another potential cause is dirty guide bar grooves and oil passages, which require cleaning. Lastly, the automatic oiler flow might be too low, so increase the oil flow.

  If your Craftsman Chainsaw engine lacks power or stalls, the issue might be old or improperly mixed fuel (over 30 days). In this case, drain the fuel tank and add fresh, properly-mixed fuel. A dirty air filter can also cause these problems, so clean or replace the air filter. The spark plug might not be working properly, so refer to the section on maintaining the spark plug.
