The ailment described are the symptoms of a restricted exhaust. The most common offender in this regard is the spark arrestor screen. My Echo trimmer has done it twice. The first time, I cleaned the screen. The second time, it got the heave-ho.
If it were a dirty exhaust port a new carburetor would not make it run better. Once again the shop is going to put a new carburetor on it. We are still not having problems with the 266 nor the 225. In fact I bought a new PAS 266 unit today. We had gotten down today where we only had two trimmers that would run.Dirty exhaust port
I am not sure what happened to the one with the broke bolts. Could have been 100 different things. As for the Echo 280 I have no clue why it won't stay running either.Not to sound accusing, but are people gentle with them? Do they bounce around in the trailer? Get dropped?
