Hi all, I’ve got an Echo PE 225 stick edger that has run great for the past 12 years, but recently it will start and run at a very high RPM and then die within 30-60 seconds. So far I have replaced the carburetor, spark plug, fuel lines, and air filter. I also took apart the exhaust to check the spark screen - looked clean. After all that, I’m having the same issue. Anyone have any ideas on what might be causing this? Thank you!
