  1. Stihl Fs70 Carb Adjustment

    Weedeater Forum
    I have a Stihl FS70R. I did not use it for a few years and it was running rough. I cleaned the carb, air filter and new spark plug. I adjusted the idle speed and it runs good. I noticed it is using fuel excessively and looks like the exhaust is oily. I use pre mixed 50:1 so that’s not the issue...
