Echo 755 loses power when hot...

Not the spark arrestor screen....Seems to run again OK when it cools off a bit, starts right up, then loses power again after a few minutes of full power. Before the day ended tried to run at 3/4 power for a while, that seemed maybe to work not sure. Problem seems to be when running WTF open.
Any suggestions?

Take a compression text see if it's good. If OK next step
If you have another blower the same running good just swap the carburetor for text . You problem should be the carburetor

Don't have another Echo, only Sthil.
How does the carb fail as it gets warm/hot?

Echo has a lifetime warranty on coils, same as stihl. You can't just take the coil in, ya gotta hand em the machine so they can " check it out"$$.

Did you check it for spark when it quits?? Pull the plug and use a spark checker.
The plug will do, but its not very accurate.

Doesn't quit, just loses 90% of power, so spark checker will still show spark?.

Are there any damp or oily spots around the carb or the head.??
Could be a leaky intake ...isoblock...or head gasket...that seals when it is cold..and progressively gets worse as the unit warms up..
