Hello, new member here so be kind...
I have two FS-90R trimmers, both about 5 years old. Have had pretty good luck with them over the years, but in the last year they have been getting harder to start and keep running. Just dusted them both off for the spring, put in new fuel (with 2 cycle oil), checked spark plugs (new last year), reset governor to factory settings (both H & L: to 3/4 turn open), cleaned air filter). For clarity, I'll call them trimmer A and trimmer B:
Trimmer A: Starts easily in full choke, continues to run when choke put in run, but dies in about 5 seconds regardless of throttle position.
Trimmer B: Starts easily in full choke, runs great under load in run at full throttle. But after about a minute of run time, slows down and dies.
Recommendations? I'm handy and can repair, but I am admittedly not a small engine mechanic so could use any pointers from the crowd. Trying to avoid several hundred dollars of labor at the local Stihl dealer...
Thanks!
