How to start a Homelite Trimlite UT20004 Trimmer that won't start?
- J
  Jerry JohnsonJul 29, 2025
  If your Homelite Trimmer's engine won't start, begin by checking for a spark. Remove the spark plug, reattach its cap, and place it against the metal cylinder. Pull the rope to look for a spark at the plug tip. If no spark appears, try again using a new spark plug. Also, push the primer bulb until it fills with fuel. If it doesn't fill, the primary fuel delivery system might be blocked, and you should contact a service dealer. If the primer bulb fills, the engine could be flooded. In that case, squeeze the trigger and repeatedly pull the rope until the engine starts. Keep in mind that depending on how flooded the engine is, this may require many pulls.

What to do if the string will not advance on my Homelite Trimlite UT20004 Trimmer?
- J
  Jason HessAug 8, 2025
  If the string on your Homelite Trimmer won't advance, try these steps: First, lubricate the string with silicone spray if it's welded together. If there's not enough string, install more. If the string is worn too short, pull the strings while pressing down on and releasing the spool retainer alternately. Remove and rewind the string if it's tangled on the spool. Finally, make sure to advance the string at full throttle.

Why Homelite Trimlite UT20004 engine does not reach full speed and emits excessive smoke?

  If your Homelite Trimmer's engine emits excessive smoke and doesn't reach full speed, make sure you're using the correct fuel and fresh 2-cycle oil mix (50:1). Also, clean the air filter. If the issue persists, contact a servicing dealer to check the spark arrestor screen. Additionally, inspect the spark plug; clean or replace it and reset the spark plug gap.
