It's octagonal: from the Latin "octo", which means eight (8) and "n-gon" where n is the number of sides. Thus, an octagon is an 8-sided polygon, like a typical "stop" sign in the USA. Think of any 6-pt socket, but imagine it with 8 points instead of 6. Now, try to make the six-sided "tool"...

I don't know about the FS-111R, but I had a pole saw with a similar powerhead on it, think it was an HT-131 maybe. I went to tune the machine for resale, and it just didn't seem to want to tune, seemed sluggish to rev up, didn't seem to run WOT like I thought it should either, much of what...

UPDATE to the issue with this MS-180: Success! This saw runs flawlessly now, and there's no more spitting oil and fuel everywhere. What I did: ordered a Walbro WT-215 carburetor, made the modifications to the air box and the housing to gain access to the H, L, and LA screws. I also added a...

There's no scoring of the piston or cylinder walls. I've looked at it through the intake side, the exhaust side and through the plug hole - my camera picks up every single minute detail in an object photographed. I know scoring can happen fast, and I've repaired saws that have severe scoring...

It is a ZAMA on it from Stihl: C1Q-S152E - came that way from the dealer less than 2 years ago

I'm with you! This one has me puzzled. I've read of folks changing the mixture settings via internal adjustments to the carburetor, but that is outside of my wheelhouse - I can rebuild the carburetor, but I don't like tinkering with all those little parts to begin with. Making changes to them...

Sorry everyone - forgot to attach the photos, but they're in the post now :-)

I'm using Stihl brand 50:1 ratio oil with non-ethanol fuel. I am no stranger to Stihl 2-strokes and have had dozens of them, work on all of my own equipment, even rehab old and damaged Stihl equipment as a sideline. This is something different. I'm OCD with my fuel/oil mix cans: I only use...

Hey everyone, I've got a problem with my little MS180 that I can't figure out. When running, it spits a nasty, oily black mess out of the muffler. It's clearly coming through the combustion chamber since it's so black, but why is this happening? I can only surmise that it's running way too...
