Had issue with Stihl FS46C weed wacker. Ran rough and hard to start. Eventually found OEM carb on
Amazon and decided to try it for only $20. It was easy to replace and it magically fixed the issue and it’s running as if it was new.
Was hesitant when dealer stated that I shouldn’t trust these and they could cause more issues. I figured it was worth the attempt since it would cost more to have them fix it and since it’s over 6 years old I said what the heck and bingo it was a good decision.
