Our Stihl
FS-90R weed trimmer is just over 4 years old and still runs great!
The trimmer head needs to be
replaced. I was going to order an after market trimmer head on Amazon
but changed my mind when I saw all the bad reviews.
Better to wait and pay a
little more at a Stihl dealership. My new favorite place to take Stihl
products is the feed store in Gate City.
After having owned and used several other brand trimmers, chainsaws and other assorted equipment and suffering the associated failures of the same machines I started buying Stihl--(buy once cry once!). They start everytime, they perform better than expected and last forever--provided you do the maintenance. I was advised by my local Stihl dealer to not use automotive gas if at all possible and never store the equipment with automotive gas in it or run it empty to store. They advised using the premixed canned gas ($10.99 per quart--ouch!) all the time and at the very least to store it with the canned gas. So now when I'm ready to store my equipment until next season I run it until empty and then add the canned gas, run it again for 10 minutes and put it away. Next spring it starts right up. I have the same trimmer you have and it's a workhorse! Enjoy your blog. Keep up the good work! Regards, Ken and Robin http://fromheretoappalachia.blogspot.com/
I'm on my 2nd or third weed eater from Stihl...can't be beat. I agree, do not buy an off brand cutter head. I know you like to experiment, as I do, but my experience convinced me that the engineers at Stihl know better than anyone what works. Also, do you use non-ethanol gas? And if not, do you use fuel stabilizer? I learned the hard way. Use it or your carburator will be toast in just a few short years. Keep up the good work.
