Homelite string trimmer - suddenly sputters off-idle

Hello all...first time poster here!

I have a Homelite String Trimmer that is about 3 years old (I think)...I can post model and engine info tonight when I get home...

Yesterday, I used it for the first time this season. It had about a half tank of gas in it, but I always put a little Stabil in my 2-stroke gas. I topped it off with fresh gas, primed it, and it actually started on the 4th or 5th pull. I was pleasantly surprised considering it had been in storage for 6 months.

It took a while to get warmed up and run well, but it did eventually. I probably used it for 20-30 minutes - mostly wide open throttle and working it pretty hard, as I have a lot of weeds to "whack".

Suddenly, it just started sputtering and missing, and would barely turn the trimmer head. It still idles just fine, but as soon as you pull the throttle trigger, it starts running very badly.

I can't say for sure if I did anything (like hitting a small stick or a pile of dirt with the trimmer head)...

Does anyone have any idea why this would happen so suddenly? I am guessing there is something going on with the carbeurator, but I am not sure.

Any ideas are greatly appreciated!

Hello Jeff! And welcome!

It really sounds like your muffler is clogged. Maybe something (like a bug...maybe mud dauber wasps) built a nest inside the muffler and it fell apart suddenly and clogged it.

Question Homelite Trimmer - Sputtering - UT20811

I am found this thread researching the a similar problem I am having with my relatively young Homelite string trimmer.

I took off the muffler, started it and still had the same problem of sputtering & missing at idle and worsenting as I increase throttle.

Any ideas on what to check next? I put a new plug in and new gas. I also checked to fuel line for cracks, checked the air filter, looks ok.
