Echo Trimmer Won't Start

He said that he replaced the carb and still no start.

10-4 ..it maybe more of an expense than it's worth .

Take the plug out and hold your thumb over the hole while you pull the starter to test compression. . If you can keep your thumb on the hole its no bueno

More than likely the rings are shot. If it was run on straight gas its toast. You have fuel and fire my guess is no compression.

You can replace the ring, piston, and stuff like that yourself. Get online and get the parts. Those most engines like that aren't overly complicated.

Yeah, I started to recommend comparing prices earlier on ereplacement parts.com

Short block may not be needed, but here it is just in case.

OK, I have taken it apart and the piston is definitely scored. Cylinder seems pretty smooth. I'm gonna get a piston kit and try that.

You can screw a compression gauge into the spark plug hole and find out real fast if there is a piston/cylinder issue. I would replace all fuel lines. Cheap, easy, can cause described problems, and will let you rule that out.

If it's priming properly, it most likely wouldn't be that though. Also, isn't a compression test best done after the engine has warmed up?
