Stihl or Husqvarna trimmer?
Comments (12)I ended up buying a Stihl FS55R and promptly returned it the next day. Would not start at all.The dealer looked at the plug and found that it was bad from the factory (electrode broke off). Put new plug in. He then finally got it started and all it did was shake violently. He offered me either a new one or my money back. I took the money. I have a love/hate relationship with Stihl. My Stihl saw works great. I had considered an Echo or Deere but after reading several post here I bought the Stihl. When the Stihl equipment we have at work is actually working, they all run and start great. We do have a high break down rate though. To make a long story short I then bought a Husqvarna 223L and am very pleased. Started on the second pull out of the box and starts on either the first or second pull every time since (following the start procedure as the manual recommends). Good power and rpms as well. The older FS55R/C that we have at work runs like a scalded dog and starts on the second or third pull every time. I had hoped that the FS55R I bought would be similar....See MoreStihl Grass Trimmer Won't Run at High Speed
Comments (10)If the trimmer ran fine with your fuel mixture screws set to where they are now, you really shouldn't have to mess with the fuel mixture screws. If it bogs and dies when you give it part throttle, does it run a little better with the choke half way? If so, take the carb off and clean it out with carb cleaner and put on a new fuel filter. If it still won't run, clean the spark arrester....See MoreStihl FS55Loop or Echo SRM 210 string trimmer?
Comments (53)I realize this is a very old thread, but for the benefit of those reading reviews I thought I would share my experience. I've owned several Echo 210's. In terms of reliability the little echo is amazing. Not once in 12 years has an echo trimmer failed me in the field. I've had issues. Even broke a plastic piece on the carb that holds the throttle cable, even so I was able to put a zip tie on it and finish the day. And if I'm honest it broke due to my piling other tools in the back of the truck. Not Echos fault. The 210 is not exactly a powerhouse... Hey it's an entry level semi-pro tool. Echo should advertise them as "It just works". Year after year, use it knowing it will get the job done. In 2008 I bought a bigger Redmax trimmer. A bcz2401. Power on the Redmax was astounding, for a while. In all the years I've owned Echo, none have broken or failed under warranty. Redmax has failed in the field 5 times. Issues ranging from clogged screen to coil failure. Not once have I clogged a screen on an Echo exhaust. While it isn't hard to fix, it just shouldnt happen. Recently the Redmax failed again. It's out of warranty, but still very low hour (I've gone back to using the Echo). After this most recent failure I almost recycled the Redmax, it simply fails too often. I decided to try having it serviced by another dealer. The "new" service center recommended a carb kit, in installing it they found a defective diaphragm. Hopefully it will run as it should, but I will never have the confidence with it that I have with an Echo. Year after year, Echo just works. If it doesnt, I've yet to be disappointed by the installation of an "Echo re-power kit". It comes with everything to restore the original power (spark plug, air filter, fuel filter.) Also in 2009 I bought a Stihl fx 110. Maybe it wasnt setup properly from the dealer, others have said it should have lots more power. By the end of the first day the Stihl was in the back of the truck, my helper was using the old (6+ seasons) Echo. I probably sound like a company schill, but for my money and peace of mind, Echo is the clear winner. Btw if you regularly cut very tall or super thick grass the 230 is much torquier than the 210. It's surprising that such a small difference in cc delivers so much power. The 260 is simply a Hoss....See MoreStihl Trimmer FS80
Comments (20)Hi Ian, On your stihl fs80 trimmer you first need to check for spark and compression. To check for compression w/o a gauge; remove the spark plug and then hold your thumb over the sparkplug hole while turning the engine over with the pull start. You should not be able keep all the pressure in the cylinder with your fingertip no matter how hard you try. Next, check for spark by putting the plug back on the wire but do not thread it in to the cylinder. Touch and hold the threaded end of the plug to the cylinder and then pull the engine over with your other hand and look for a spark at the tip. You may also be able to hear the spark if its good and hot. I hope you had some oil mixed with your gas when you had that trimmer running? If not its going to be needing a set of rings. I would also replace the fuel line going from the filter to the carb, and wash out or replace the filter. The carb jet which is closest to the cylinder is the low side, with the other as the high side. Rotate each in to the cylinder with a screwdriver while turning clockwise untill the jets seat. Next turn each jet out 1 and 1/2 turns to start. This will get the engine running. Allow the unit to warm up for a minute and adjust the low side jet clockwise by 1/8 turns for the highest idle speed. Once you have attained the high idle, back the jet out an additional 1/8 for good acceleration. Next is the high side, go to full throttle and adjust for highest speed. Again back the jet out an 1/8 turn counter clockwise from highest rpm to keep the high side from being too lean under a load. Hope this helps you sort it out. Make sure you use a quality air cooled engine oil for your fuel mix. If you have any questions please post them. Best wishes, Bob...See Moreandy_levine
