My weedeater featherlite xt260 dies when I press the throttle. It starts OK but will not
Increase in speed and just stalls out. It will start again right away but that is it.

Temporarily remove the air filter and try to start the eater. Is there any improvement at all? Come back with your results.

I will try it and get back to thanks

I Believe You Will Need To Clean Your Carb. Or Have It Adjusted. The Other Thing I Think It May Be Is The Spark Arrestor In The Muffler Stopped Up. I Do Not Think You Will Have An Improvement By Removing The Air Filter, That Just Doesn't Seem Like The Problem You Describe.

Mowerman, you may be correct. I wanted to first eliminate a plugged air filter, sounded like it might be starved for air.

I agree with Mowerman. I took my Stihl weedeater to the dealer with the same problem and they replaced the spark arrestor screen... runs great.

O.k. Ballengerb 1, I See What You Were Saying. Good Answer.

Sorry for the delay in answering I have been pretty busy.

Thank you for the replies.
I was looking at the adjustments on the bottom front of the carb. There are two of them. You need a special tool to turn them. They are no doubt the air/fuel. I pulled the bottom plate off the carb and use my Dremel tool to cut slots in the heads. I put it together and started it up. Opened the throttle all the way and turned the outer screw about an 1/8 of a turn. The engine responded immediately problem solved. It might be a little rich but rich is better than lean. A guy at work showed me that trick, he uses it on his chainsaw.
Thanks again
