Why my Craftsman CMXGTAMD25CC engine will not start?
- A

  If your Craftsman Trimmer engine won't start, several factors could be at play. First, ensure the fuel tank isn't empty; if it is, fill it with properly mixed fuel. If the tank is full, try pressing the primer bulb 10 times, or until you see fuel. If the engine is flooded, move the choke lever to position 3, press the throttle lockout, squeeze the throttle control, and pull the starter rope until the engine starts. Old or improperly mixed fuel can also be a culprit, so drain the tank and refill with fresh fuel. Lastly, a fouled spark plug might be the issue, in which case you should replace it.

  If the cutting head on your Craftsman Trimmer isn't advancing the line, several issues could be responsible. Here's what to check: * The cutting head might be bound with grass: Stop the engine and clean the cutting head. * The cutting head could be out of line: Refill the cutting head with new line. * The inner reel might be bound up or the cutting head is dirty: Clean the inner reel and outer spool. * The line is welded: Open the cutting head and remove the welded section. * The line is twisted: Rewind the line. * Not enough line is extended: Stop the unit, push the bump knob, and pull the line until 4 inches (102 mm) is outside of the cutting head.

  If your Craftsman Trimmer engine isn't accelerating, consider these potential issues: old or improperly mixed fuel might be the cause, so drain the fuel tank and add fresh, properly mixed fuel.
