i have a echo that is hard to start. once you do start it i will run on full throttle for a few secounds and then die. so far i have replaced the spark plug and checked the muffler for build up, it was clean. what should i try doing next?

Check your fuel lines for any cracks or holes. My chainsaw did the same thing and I found a pinhole in the supply fuel line. I replaced the line and problem was solved.
