Why my MTD Yard Machines Y28 engine will not start?

  Andrew RamirezJul 30, 2025
  If your MTD Trimmer engine won't start, several factors could be at play. First, ensure the fuel tank isn't empty by filling it with properly mixed fuel. If that's not the issue, try pressing the primer bulb fully and slowly 10 times. In case the engine is flooded, squeeze the trigger and pull the starter rope. Old or improperly mixed fuel can also be a culprit, so drain the gas tank and add a fresh fuel mixture. Lastly, a fouled spark plug or a plugged spark arrestor can prevent starting, so replace or clean the spark plug and clean or replace the spark arrestor.

To address this, start by draining the gas tank and adding a fresh fuel mixture, as old or improperly mixed fuel is a common culprit.

  If your MTD Trimmer engine will not accelerate, there are several potential causes. Start by draining the gas tank and adding a fresh fuel mixture. If that doesn't solve the problem, the carburetor might need adjustment by an authorized service dealer. Also, check the cutting attachment for any grass binding it, and if so, stop the engine and clean the attachment. Lastly, a dirty air filter or a plugged spark arrestor can hinder acceleration, so clean or replace these components as needed.

  If your MTD Trimmer engine won't idle, several factors could be responsible. Begin by checking the air filter and replacing or cleaning it if it's plugged. Another common cause is old or improperly mixed fuel, which requires draining the gas tank and adding a fresh fuel mixture. If these steps don't resolve the issue, the carburetor may need adjustment; refer to the Carburetor Adjustments section for guidance.

  If the cutting attachment on your MTD Trimmer will not advance, several issues could be the cause. First, stop the engine and clean the cutting attachment if it's bound with grass. If the cutting attachment is out of line, refill it with a new line. For an inner reel bound up, replace the inner reel. If the cutting head is dirty, clean the inner reel and outer spool. If the line is welded, disassemble, remove the welded section, and rewind. If the line is twisted when refilled, disassemble and rewind the line. Lastly, if not enough line is exposed, push the bump knob and pull out line until 4 inches (102 mm) of line is outside of the cutting attachment.
