remove the sparkplug and try to turn the flywheel if it turns freely then the engine is most likely ok. if it does not turn you have a locked engine that means its toast. If it does turn then you have to look closely at th pull recoil that it is engaging the flywheel.

Fuel lines could be collapsing from being soft, mush from ethanol in gas, possibly you have wrong carb kit, or something put together wrong, fuel lines reversed, double check everything then make sure you exhaust screen is not plugged, cause this will do same thing.

The blower is a 2 cycle, so you run an oil and gas mixture. Here is the link for the owners manual.

50 to 1 don't use outboard 2 stroke oil. Use good oil echo, still, Husq ect.

Sounds like there is something either broken,stuck or missing in the head.

Recheck the line replacement. The twin line feeds are tricky. The videos should help. https://www.google.com/search?q=echo+gas+2+line+string+trimmer+line+replacement

I know this is a very old post, but figured I'd answer it so any others with this issue can have the fix. With Echo trimmers not revving to speed although they start with no problem, the issue is usually the muffler screen. It becomes plugged with carbon because of improperly mixed 2 stroke fuel. Remove the screen from the muffler and burn off the carbon with a propane torch, or wire brush it off. Once cleaned engine should rev to speed.

Classic sign of coil failure. Run it until it cuts off then test the coil. Most likely 0 resistance, complete open circuit. This is common, coil can't be repaired, only replaced. It is a simple fix, and echo trimmers I believe are worth the cost of coil to repair. Plenty of youtube videos on how to do this repair.

The most common cause is a wood chip stuck in the inlet or exhaust valve. Check the compression.

Check the fuel lines. Make sure the pickup tube (line with the fuel filter) has not fractured.
