  Linda CervantesJul 30, 2025
  If your Yard Machines Trimmer engine lacks power or stalls when cutting, the issue might stem from old or improperly mixed fuel; in this case, you should drain the gas tank and add a fresh fuel mixture. Another potential cause is an improper carburetor adjustment, which requires taking the trimmer to an authorized service dealer for adjustment. Additionally, a fouled spark plug or a plugged spark arrestor could be the reason, so you should replace or clean these parts.

  If your Yard Machines Trimmer engine will not accelerate, there are several potential causes. Old or improperly mixed fuel is a common issue, so drain the gas tank and add a fresh fuel mixture. The carburetor may also need adjustment, which should be done by an authorized service dealer. Additionally, check if the cutting attachment is bound with grass and clean it if necessary. A dirty air filter or plugged spark arrestor can also restrict acceleration, so clean or replace these parts.

  If the engine of your Yard Machines Trimmer won't idle, the air filter might be plugged, so replace or clean it. Also, old or improperly mixed fuel may be the cause, requiring you to drain the gas tank and add a fresh fuel mixture. Finally, the carburetor adjustment may be improper and you should adjust it according to the Carburetor Adjustments section.

What to do if the cutting attachment will not advance on my Yard Machines Y765 Trimmer?

  Renee MartinezAug 17, 2025
  If the cutting attachment on your Yard Machines Trimmer won't advance, it could be due to several reasons. First, check if the cutting attachment is bound with grass and stop the engine to clean it. Other potential causes include the cutting attachment being out of line (refill with new line), the inner reel being bound up (replace the inner reel), a dirty cutting head (clean inner reel and outer spool), line welded (disassemble, remove the welded section and rewind), line twisted when refilled (disassemble and rewind the line), or not enough line exposed (push the bump knob and pull out line until 4 inches (102 mm) of line is outside of the cutting attachment).
