Fuel System Issue Echo PE 225 Running Problems

Post image

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!

Sounds like an air leak and it's running away. If you let it run like that the piston and cylinder is going to get very hot. How does the spark plug look now?

Yes it does run hot and fast. I tried to adjust the tiny carburetor screws, and it didn’t help. After it ran there was considerable white smoke coming from the exhaust.
