    How to fix Homelite UT33650 when the engine will not start?
    • C
      Cynthia VazquezAug 18, 2025
      If your Homelite Trimmer's engine won't start, there could be several reasons: 1. **No spark:** Clean or replace the spark plug and reset the spark plug gap. 2. **No fuel:** Push the primer bulb until it is full of fuel. If the bulb doesn't fill, the primary fuel delivery system might be blocked. 3. **Engine is flooded:** Set the choke lever to the START position, squeeze the trigger, and repeatedly pull the starter grip and rope until the engine starts. This may require numerous pulls.

    Why Homelite UT33650 Trimmer engine will not start?
    • J
      Jacqueline RamosAug 20, 2025
      The Homelite Trimmer engine might not start due to several reasons. There could be no spark, which requires cleaning or replacing the spark plug and resetting the spark plug gap. Another reason might be no fuel; in this case, push the primer bulb until it is full of fuel. If the bulb does not fill, the primary fuel delivery system is blocked, and you should contact an authorized service dealer. Finally, the engine may be flooded. To resolve this, set the CHOKE lever to the START position, squeeze the trigger, and pull the rope repeatedly until the engine starts and runs. Note that depending on the severity of the flooding, numerous pulls of the rope may be required.

    What to do if the line will not advance on my Homelite UT33650 Trimmer?
    • T
      Tyler NelsonAug 23, 2025
      If the line on your Homelite Trimmer won't advance, here are a few possible solutions: 1. **Line is welded to itself:** Lubricate the line with silicone spray. 2. **Not enough line on spool:** Install more line. 3. **Line is worn too short:** Pull the lines while alternately pressing down on and releasing the spool retainer. 4. **Line is tangled on spool:** Remove the line from the spool and rewind it. 5. **Engine speed is too slow:** Advance the line at full throttle.

    What causes a hard to turn spool retainer on Homelite UT33650 Trimmer?
    • A
      Alejandra AustinAug 26, 2025
      If the spool retainer on your Homelite Trimmer is hard to turn, it's likely that the screw threads are dirty or damaged. Clean the threads and lubricate them with grease. If there's no improvement, replace the spool retainer.

    • P
      palmerandrewAug 30, 2025
      If the line on your Homelite Trimmer will not advance, consider these potential causes. The line may be welded to itself, in which case you should lubricate the line with silicone spray. It's also possible that there is not enough line on the spool, so install more line. The line may also be worn too short, so pull the lines while alternately pressing down on and releasing the spool retainer. Another reason could be that the line is tangled on the spool, so remove the line from the spool and rewind it. Lastly, the engine speed may be too slow, so advance the line at full throttle.

    Why does my Homelite UT33650 engine not reach full speed and emits excessive smoke?
    • K
      Kevin PetersonSep 4, 2025
      If your Homelite Trimmer engine doesn't reach full speed and emits excessive smoke, consider the following: 1. **Incorrect lubricant/fuel mixture:** Use fresh fuel and the correct 2-cycle lubricant mix (50:1). 2. **Air filter is dirty:** Clean the air filter screen. 3. **Spark plug fouled:** Clean or replace the spark plug and reset the spark plug gap.

    Why does grass wrap around the drive shaft housing and string head of my Homelite UT33650?
    • R
      Robert SmithSep 7, 2025
      If grass wraps around the drive shaft housing and string head of your Homelite Trimmer, it could be due to: 1. **Cutting tall grass at ground level:** Cut tall grass from the top down to prevent wrapping. 2. **Operating trimmer at part throttle:** Operate the trimmer at full throttle.

      Lisa SmithSep 9, 2025
