I have had my Troy Bilt trimmer for about 6 or 7 years now and it never fails each year I have to clean the carb to get it to start for the first time of the season. Thanks to the ethanol fuel we have all been blessed with and the fact that I am never on top of the maintenance thing to either make sure I start the stuff and run it once or twice a month or drain the gas out all the time.

Dad has a two stroke trimmer he bought a while back as well but I gave up last year trying to get it running. The Troy-bilt did alright but it is one of the bent shafts and it lacked power most of the time. I decided it was time to get another trimmer. I wanted something that had a shoulder strap and I was also going to get one with the bike handle bars. Where I work at is a Stihl dealer so I went over to the show room.

My plans were to get an FS 130 with the bike handle bars. I picked the display up and it just wasn't comfortable so I picked up the FS 90R which has the loop handle and it was a little lighter and I liked the loop handle a little better. The more I thought about it, it isn't like I do commercial lawn care and am out there trimming 8 hours a day.

I also read up that the FS 90 and FS 90R are usually the ones that the commercial lawn care crews will have on the truck for trimming. So the FS 90R came home with me. Hopefully this will be the last trimmer I will need for a long time. I also picked up another 6 pack of synthetic oil for the trimmer and my Stihl 362 chainsaw. I did fire up the trimmer when I got home. A guy needs to play with a new toy right?

The Stihl trimmer seemed to do very good. I am curious to see how it does once it is broken in. It is definitely more powerful then the Troy-Bilt I had. I guess time will tell. The shoulder strap does make it very nice and hopefully my arms won't give me any fits. I have carpal tunnel in both hands so I could only ever use the trimmer or any engine powered tool for maybe a half hour max before I would have to put it down and walk away. At least not the strap will take most of the weight which should help I hope.

I should also add that the FS 90R was about $130 cheaper then the FS 130 which played a big factor in the decision. That and I think the 130 would have been overkill for what we need it for. I am looking forward to getting one of the brush cutting blades though and see how it does cutting down some of the little pine tries that are growing along the fence line. I did pick up one of the three plastic blade trimmer heads for it too. I can't stand those thick weeds that refuse to be cut with a normal trimmer string.

Do you run stabilizer in the fuel, all the time?
Starbrite Ez to Store
or SeaFoam.

I does make a big difference, with this ethanol fuel.

Looking forward to some pics of the new toy.

We do seriously try and put seafoam in them but don't always remember. I do need to get better with this as maintenance on them all the time because of the ethanol fuel does suck.

I will try and get a couple pics tomorrow. I already got it dirty so it won't be as purty LOL.

Hope you enjoy your new toy. I get trimmers all the time that have just been sitting then one day the owner picks it us and wonders why it won't fire up. A good stabilizer is the answer, I leave fuel in my old weedeater brand trimmer over winter and it fires up in the spring.

The other thing I didn't realize is the trimmers except for the FS 250 are all 4 mix. I guess it is Stihl's terminology for a four stroke that uses mixed gas like a two stroke. I am used to the four stroke style trimmers though because that is what the Troy-Bilt was. But the Troy-Bilt had a crankcase for separate oil and gas.

The rule around here is, "you fill the Jerry can, you stabilize it. Period"

I add the Seafoam to the empty cans before I go to fill them! That ensure that they are well mixed and stabilized from the time they leave the pump!

That is a good idea/ habit to get into.

Just a little FYI, if you run Stihl mix oil it has stabilizer in it already. So no need to add anything.

But 2 years ago at work we switched to amsoil saber 2 stroke oil and have never been happier. We have reduced our repair costs considerably. It is 100:1 but it works great in all modern Stihl products.

Sounds like a nice trimmer George. The other day I was listening to an automotive repair phone in and the expert they had there commented that he does not use regular grade fuel but uses the mid grade because according to him the mid grade does not have the Ethanol mixed with it like regular does. That may be specific to this market but he's a well respected veteran of the automotive industry and usually has this stuff correct. I'm switching to mid grade for my mix gas and tractor gas to see if it makes a difference. One good thing is with all that Ethanol in the regular gas you shouldn't need to worry about adding antifreeze (methanol) in the winter.

I have been running the AMS Oil 50 to 1 mix for several years and always use 89 octane gas both on the golf courses and at home. I was told that mixed fuel should have 89 octane gas simply because mixing the oil with the gas lowers the octane rating. Makes sense to me. Plus since using the AMS Oil and 89 gas I have never had a two cycle engine failure except where the operator used straight gas.

Thanks Bill. I know the newer oils don't make much smoke. Maybe it's the mix ratio. I've been using the Stihl oil in my chainsaw. I'm only using it for property maintenance but the big issue I've always found with 2 stroke engines is fuel and carb problems when you let them sit for any extended period.

George you will like the Stihl! I used to think they were over rated, until I bought a Stihl Chainsaw a year ago.
They are everything they claim to be!! When my throw away Homelite gives up Stihl is the one I'll be getting.
As for the ethanol, I live in a town of 16,000 population and there is only one station that sells anything other than 10% ethanol.
Little choice in my case.

I dont use my trimmer much, but I would love to have stihl. I have a poulan that is like most trimmers, a pain to get running unless you use it every few days.
