When I run my Stihl FS-90, the trimmer head spins and it is revving pretty hard while idling. This seems to have started happening after I did a tune-up (spark plug, fuel filter, air filter). Not sure what could have made it happen, I thought maybe I accidentally turned the carb screw.
I have tried adjusting the idle screw, and turning it does at affect the idles RPMs at all.
That's what it sounds like
