My trimmer needed the carburetor changed. I bought one of ebay from one of the Chinese businesses. It works until trimmer starts warming up then it sputters and dies.
.....you never know with those China things :/

I find that the primary advantage to after-market carbs is that the EPA adjustment lockouts have been eliminated.
Have you tried tweaking the mixture adjustment?
Be careful when following the masses. Sometimes the M is silent.
Mixture needs adjusting.
Eeewwww, don't touch it!
Here, poke at it with this stick.
The idle speed may also need to be brought up some if its running when chocked.
Bring the idle speed up then adjust the mixture and bring the idle speed back down if needed.
I have bought several of these china carb kits and have had no issues once adjusted.
The cost savings is good.
It I had to pay state prices I'd probably just trash the unit and buy another trimmer.
I replaced the carb on my Echo trimmer a year ago. It was $15 on Amazon. Seems to work just fine.

I finally got tired of cheap junk trimmers. Went and bought a Stihl from my local dealer. Bought an extra six pack of oil and they gave me an extended warranty of like two or three additional years... Never had a trimmer with a warranty before.
I have never seen a small engine that didn't require or at least benefit from a carb adjustment after break-in or for your particular fuel source or from 100° summer to freezing winter use. My local Stihl dealer told me it was "illegal" for him to sell me an adjustment tool for my chainsaw. Said I had to bring it to him. So I ordered one from Amazon.
Deplorable before deplorable was cool!
Went through all this with three different small engines this summer.
I tried the cheap carbs with poor luck.
Instead, I bought carb kits, Walbro or Zama, and rebuilt the OE carbs.
Also, starting next season, I am done using pump gas with ethanol. I am going to find a local source for ethanol free fuel.
I stored all these engines for the winter with a fill of TruFuel.

Some of the best advice in this thread. Lose the alcohol.
I'm not completely useless. I can be used as a bad example.
I can't answer the original question, but it really pays to find a source for ethanol free fuel. I have a chainsaw, weedeater, and push mower that have run for better than 10 years now with no maintenance at all. I run ethanol free fuel and add Sta-Bil for Winter storage. None of them have ever failed to start within 2 pulls when I pull them out the first time in Spring.

"Odd," said Arthur, "I thought you said it was a democracy."
"I did," said Ford, "it is."
"So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't the people get rid of the lizards?"
"It honestly doesn't occur to them. They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates the government they want."
"You mean they actually vote for the lizards."
"Oh yes," said Ford with a shrug, "of course."
"But," said Arthur, going for the big one again, "why?"
"Because if they didn't vote for a lizard, then the wrong lizard might get in."
Have you checked to see how much a carberator is from the dealer? It might not cost too much.
Sounds like yours just needs the high speed mixture screw adjusted out a 1/4 turn or so. When it is hot, put the choke half way on and see if it stays running at speed. If so, the mixture screw needs to be adjusted out a little to provide more fuel flow.
