I've been considering building a 125 piped saw since I do find these engines about for cheap:

Took me a while to find this: I think that's a ported Honda MT-5. 50cc. That look anything like a 346xp? It produces about 4-5X the power of a 346xp and has no less than 15 ports.

It's a bit more complicated than that. Here's a place to start: Expansion chamber - Wikipedia, the free encyclopedia Motorbikes have a huge advantage over chainsaws in that they can place a large tuned expansion chamber(which some mistake for a muffler). A well-tuned exhaust can produce nearly twice the power the same engine would in a chainsaw because it frees up the design to run far more aggressive port tuning, and other port options. Boost ports become particularly effective then. In other words, a 120cc sport bike will have completely different port design and timing than your MS880 would. Notice the absolutely huge ports on this KTM 125 VS an MS880. It simply flows more fuel and exhaust, partly due to having a tuned exhaust, and partly due to weight not being a factor. [ame] [/ame]

Slapping a thong on a MILF works well, I find.

I had that squish on my 385XP, too. By comparison, the squish on my 2165 with BB kit is a huge .029" without gasket. But the .030" pop-up helps a bit on that machine.

Lathe work - .030 off the squish band, .040 off the base, very thin gasket. Squish is set to .018.

Got the MS361 finished. She's already blowing almost exactly 200 psi: I'll try and get vids as the weather permits.

With all that wood in your avatar, who has time to let fuel sit?

Traditional stabilizers, AKA StaBil does nothing for preventing ethanol reacting with air and forming water, or whatever it does. So a reformulation makes sense.

Stihl and Husqvarna both state that their full synthetic mixes and blends have a fuel stabilizer, as do many other brands.

Hell, the Pro-Lite isn't even very light weight.

I bought a saw off a guy in San Antonio, Texas a few years back that used carbide chipper chain to cut railroad ties with. He said they lasted quite a bit longer between sharpening. He showed me some of their work saws, and the amount of tar and creosote and gunk on them was stunning.

Most two stroke mix come with stabilizer.

And they'll do one for you, too ...for $190... *cough*

Why do you have to pinch it when you can just fabricate one They look better on the 440, anyways:

In practice, the adjustment works fine if you simply work in largish wood for a couple of minutes. Not using the chain brake going between cuts isn't gonna kill you. In fact, the vast majority of chainsaw injuries(over 99%) according to OSHA are non life threatening even without PPE. The chain brake use is heath and safety gone mad in the UK, and most new folks have no clue that few experienced professionals before H&S and the guilds stepped in actually hurt themselves because they didn't put the chain brake on manually. The chain brake was never meant to be engaged manually aside from starting the saw from it's inception - it came into being to control kick back, not moving from log to log or tree to tree. I was using saws before chain brakes were common. We knew how to handle the saws, and we paid attention to what we were doing. After 25 years of using saws, off and on, often in logging, I haven't touched myself with the chain once. PPE helps, but it won't make one a sawyer by itself. Personally, I think all the PPE and H&S make people more careless and less self reliant for their safety.

Sorry, mate. The only thing I have heard, but can't comfirm, is the timing is advanced a bit more so than the old 372xp. So if the key is off, I suppose it could be more bitey. Did ya remove the gasket? What sort of squish do they have? The old 372/365 chassis were not known for their compression.

Turn the piston the right way round!

It works alright. I'm not a fan of the outlet, though. I'll probably remove it, clean it up, and sell it after I replace it. For felling. She works just fine. The full wrap only adds about three inches to the side.

The Stihl part number for the dual dog and chain roller kit for the 361 from the IPL is: 1135 650 7750 I suspect the same kit for the 261 fits as well. The wrap kit, with dogs, new upper AV spring, wide clutch cover, roller catcher, and scrench and all associated mounting hardware is: 1135 007 1007 This guy has them up for sale often, and ships internationally: STIHL MS361 CHAINSAW WRAP AROUND HANDLE BAR SET ----- BOX119 | eBay

So, your question is would I rather carry on and do work with my chainsaw as it tunes itself, or fiddle with it and get no work done for a couple of minutes?

It's even worse than that. It's marketing. For some odd reason, there is a market for a mid range 70ish CC saw that doesn't cost what a pro 70cc saw does. I blame poor bastards like myself - one of my favourite things to do is turn 365's into 372's or 375's or 377's. So, Husky took their 372 XTorq and designed it to run a lower RPM, put a new sticker on it, and transfer port covers (A La Shindaiwa style), and sell it as a 365 VS 372. You CAN replace the P&C if you like. In this case, you can retain the carb and modify the intake. The XT carb is capable of more fuel and air than even what came with the 390 xp's. So this is often what some porters use on 390's if they want the thing to pull a huge bar in the PNW, let alone 372's. Having said all that, I haven't so much as hefted a 365xt. All I know is from perusing AS. I imagine, sooner or later, one will find itself in front of me. I'll post what train wreck happens then. WYK

I dunno. I actually think tubes look vulgar. I prefer louvers. When done right, they look factory and are nearly invisible. Also, being from the old Mac and Homelite club, I am used to seeing them on mufflers as factory once upon a time. Or else I try to hide the tube as much as possible...which isn't easy:

This is true to a certain extent. Of course it depends on the saw and the carb. We also have to consider the source. Saws in the States are set up from the factory to be as lean as possible. On later model carbs, they went so far as to downsize the needles. The US has an extremely tough air pollution standard, and a large enough market where manufacturers can easily tailor make the products that wortk within it. The only diesel engines that pass the EPA standards are the Mercedes and VW 2.0's. You will not see another diesel car there. It's that and the fact Americans only like Italian cars they can't afford... And, well, no really really admits they like French cars

Gonna fit a 36" bar to it and show it off on youtube?
