Wrong part
Tried twice to order my part and twice received the wrong part. Ereplacement staff were extremely helpful and made the experience tolerable even though I received the same wrong part twice under the correct part number...Staff verified thru catalog that the part number I had ordered was correct and a factory error must have occurred. Will use again and not ereplacements error to my knowledge. Full refund on item...

Rebuilt carb.
Removed engine from tube and replaced drive shaft.
Remove clutch drum cover and removed old clutch and installed new clutch.
Reinstalled tube to engine.
Connected throttle cable and ground wire.
Installed gear head spacer and cover blade and installed new speed feed head.
Started right up and ran like new.
Was a free trimmer so rebuilding it for my lawn care business made perfect sense. Spent $70 to have a $300 weed eater. ECHO ENGINES GO THE DISTANCE. just do maintenance and you can run them for years and years. One of mine is 12 years old and the other is 15 yrs old. Run them 6 days a week.
