Echo 755 loses power when hot...

[khutch]

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

[khutch]

What would be proper compression number?

Thanks for great forums!

[Landrus2]

Between 125 and 145 you good

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..

What happens when you adjust the carb to give it a little more gas?

If it's been sitting outside chances are the air filter's wet.
Remove it and see what happens.
Let it air dry, or replace it.

Otherwise it could be the coil, they're lifetime warranty.
