STIHL FS90R - who uses one?

[Merkava_4]

They're on sale right now for $299.

Have you guys had any problems with them?

They are nice trimmers if you like the 4mix engine. Which I hate by the way. It has way too much torque and not nearly enough high end power. Who wants torque on a trimmer anyway, high end power is what gets the job done. I prefer the 2 stroke stihls.

Run them with 93 octane. Keep air filter changed along with fuel filter and the shaft properly greased. Should be no problems, they are made to run wide open not quarter throttle.

I can understand not having enough top end power, but how can you have too much torque?

I'm happy to hear that I can run it wide open.

I don't use the 90's but I have owned the 110 and own the 130's. I've used the Stihl 4 mix since they came out years ago and never looked back. I rather pay more for the most powerfull 130 and have that power when I need it. The throtal is a little touchy but if you decrease the RPM its easier than raising the RPM to where you want it. The 130's will not stop for anything even 2' tall grass with 18" total line out. Use the 93 oct fuel and the synthetic Stihl oil, cost a little more but runs much longer and tons of power. The valves will need adjusting after 100 hours but that should be free where you buy the unit from.

That's good news. Do you run your 130 wide open?

[SuperiorService.110mb.com]

Only when I need to. For the most part you will find somewhere on the property you can run it wide open for a few min. If not as your walking to a different area give it some gas. They are very fuel efficent. One thing that is very important is let it warm up for about 1 min and cool down for 1 min before you turn it off. It like a car, the valves and other componints need time to heat up or cool down to expand and contract. When you buy it, fill the tank and just let it idle till you get to your first property and baby it the first few tanks to break it in and then let it have it.

I have an FS90 and an FS100RX. We also run Redmax trimmers. Two BCZ2600's and a BCZ3100. The one picked up first is alway the 100RX. It is light and powerful. The FS90 is heavier and is rarely used.

Having the most largest powered trimmer is not always the best. For the majority of the work, a small light weight trimmer works better.

I have one and love it. But Superior is right on. You have to run premium gas AND the synthetic Stihl oil in it to get the most out of it.
