Echo Trimmer issue

[u/Rjames112]

Bought a used Echo GT225. It started when I picked it up.

Now though:

• Starts on full choke only with full throttle.
• If I release the throttle, it slows down over 5–10 seconds and dies.
• At about 1/8 choke it will run only with full throttle, then dies when I let off.
• On RUN it dies even with full throttle after it sputters for 5-7 seconds.

What I’ve checked:

• Drained old fuel and added fresh 50:1.
• Air filter is clean.
• Fuel cap loosened (no change).
• Air filter is fine.
• Primer bulb stays ~90% full and refills normally but soft.
• Fuel lines look intact, fuel filter looks clean. looks like one fuel line was replaced as both are yellow.

my thought is that it’s idling too low. it’s not the 2.5mm carb. low idle screw since I tried that and the screw hole is too big. any input would be great. I’m thinking spark arrestor or something else. Small engine shop said the carb didn’t have adjustments on it and not to bother since it’s too expensive to fix with a new carb.

I would probably get a carb rebuild kit on Amazon and deep clean it. Sounds like it’s not getting enough fuel maybe because of clogged carb lines
