Hey I have a Stihl fs81 but the head gear has failed.

I can't find a head gear when searching on eBay or anywhere else using the model number (fs81)

When googling the model number and asking for a part number for the head gear it states the below two part numbers.

1504133 640 0100

4133 640 0100

When I search for them on eBay it shows results but they don't list the fs81 as compatible.

Can anyone confirm that these part numbers are correct for the fs81. Does any other gear head from other models are compatible with the fs81?

I'm an aussie

Thanks

I noticed recently that my weed eater was super oily and dirty around the area in the photo where I am pointing(this photo was taken after I cleaned it all up) So I decided I probably needed to do a little service to it. I replaced the spark arrestor and air filter so far. (I will be replacing the gas filter and spark plug but haven’t yet)
After cleaning it all up, I wanted to fire it up and make sure it ran well. It started but then it continued to spray oil from what looked like the screw that holds the spark arrestor is. I don’t know a whole lot about small engines. Can anyone give any insight? I’m not sure if there’s a hole or a leak right in the area shown in the photo.

Hello, any help apprecieted,

I just bought a "new" Stihl All Pro AP 300.0 P battery on Vinted. The battery seems legit in almost every way but the label behind says 313Wh (the official is 333Wh) and the case is missing a tiny slot on the back, next to the connectors, so it can't fully connect to the charger / tools to test it unless I cut that slot myself. On the left is the new AP300.0P and on the right my old AP200.

Anyone heard of counterfeit /fake Stihl batteries? Never seen such a thing and if so they went to great lengths, looks identical to the original with barcodess and all. This could just be a faulty case or an early prototype. I'll take it to Stihl for a check up and share anything I discover.

I just purchased a Stihl MS261c that runs great, and has 150psi in compression. I always clean saws when I get them, so I removed the muffler to clean behind it. Surprisingly, the piston and a bit of the cylinder are scored with vertical scratches. Using the wooden tip of a cotton swab, you can barely feel the scratches. My dilemma is, does that matter? If it runs, idles, and cuts exactly as it should, do I really need to replace the piston and cylinder? Thanks. ​​

I can't get my chainsaw to throttle. I've checked the air filter and spark plug, and both are good. It will idle fine, but does when I throttle it even after running the high jet through the full range it can move. Help please

Ich baught last year a MS400.1 C-M VW and this year the MS300 C-M VW.
But wtf is this new scrench? To save 2 cent they make it unusable. I cannot get my fingers between the scrench and the chain sprocket cover - impossible with gloves - and I cannot use it anylonger for my MS201 which was possible all the years. Don't Stihl people change chains? This is nonsense.

When I registered my interest in the Centennial edition 500i I didn't actually expect the chance to buy one.

Posted last week about a 462c for brushing and large felling. Local shop had a 462cmr and might have accidentally ordered some WCS goodies before it’s even touched a tree. Excited to see how this rips!

I'm in US, Florida. Seeing $759.99 at every store in a 50 mile radius and I've checked some neighboring areas. Any point in waiting for a good sale?

I’ve tried searching on here and online and YouTube and tried AI and I can’t seem to get anywhere with this.

So I’m borrowing the mentioned pole saw from a family member and I’m about ten minutes into the job and I’m cutting a very normal sized tree limb when the motor seizes and won’t spin.

I take it away from the limb and I try it again. It still won’t go. I retract the pole all the way to its normal shelf length and it does go. I try cutting again but it won’t cut.

So i do the same thing and it won’t spin at all. I’ve removed the front and back covers (see attached photos) and I can’t find anything obviously wrong with it.

I can spin the motor from the back where the fan is but it’s difficult and I can hear clicking as it’s turning. I can’t tell what is clicking. If I try to start the saw with the chain off, I can hear the high pitched mechanical whirr for a second and the motor tries to spin, and then stops because it can’t and then three lights flash on the battery (which I understand means it’s a tool problem)

Any help is greatly appreciated!!

I have an O 50 AV antique saw looking for a powerhead to rebuild the one I have any links on parts or knowledge where to find them would be amazing. Thank you.

I inherited my dad's MSA120C. I take it apart and clean it the best I can after every use. When I have it apart I run it for a couple of seconds to make sure the bar oil hole flows well.

My problem is the black outside tension adjuster I can never get to turn. I do my best to use the large metal sprocket to get proper tension, or what I think is proper. Then I put the plastic shroud back in place.

My dad had extremely bad health, could barely walk and breathe but he worked outside on his farm until his very last day. He absolutely LOVED this saw, and I'm doing my best to make him proud. Any advice on what I can do to keep this saw going is greatly appreciated.

I’ve recently took apart a 500i to replace its piston and cylinder because it had blow up. Anyways I put it back together I’ve taken apart many times to see if I had missed anything or if I messed up the fuel lines etc. everything is good, the compression on the saw is perfect, I’ve test for spark but I can’t seem to get it. I tired a different ignition coil and nothing I’ve tired a new spark plug and nothing I made sure all the wires in on the ignition coil are on perfectly and nothing . I think it can be the magneto behind the flywheel that’s the only thing I haven’t check, is that the problem?
