    Good day...

    I bought an Echo straight trimmer at Home Depot last year. It feels like it is running rich and I am getting black crud building up on the exhaust area. The air filter is clean and it gets low use. It says on the info card that came with the unit that it may need adjusting after it has broken in. I can't see any adjustment screw. How is this machine adjusted??

    thnxs for any tips.

    You probably just need to try a different kind of oil, or double check and make sure you are mixing it to the proper fuel/oil ratio.
