Yeah, they have tiny everything. Half a mil is a lot. I wonder if a different mix would help. I haven't followed what mix you're using. Is the Exhaust MM'd? That may help some.
-
Never used a 560 for any length of time, nor any other AT saw. When you say coking, do you mean there's a heavy coating of carbon inside the actual exhaust port? I port, or have ported, every saw I personally use, and these all get the polished exhaust port treatment. However, having said that, a little bit of coking in the exhaust is not any where near as bad as a little bit of burning on the bearings. Also, when you say low hours, do you have an hour meter/tacho gauge attached to your saw? I was considering permanently attaching a TTO or WORKS gauge to one of my saws to keep track of usage.

Mitch back in the States has answered the "What to do when your internet is down" question:
-
Never had problem with coking at 32:1. In fact, it is all I run. 50:1 in a saw, like a 550 XP, that uses less fuel to start with than previous generations is asking for trouble, if you ask me.
-
I'm fond of the Shindaiwa 452 or Echo 500 for such work. Both weigh less than 11 lbs, and have far better grunt than the 35cc offerings.
-
Spud can make that 365 use a 28" bar, though.
-
Protecting valves is unimportant. Octane, however, is just as important to a 2t motor. Combustion temperatures are also very important(and the both will go hand in hand at causing detonation in your chainsaw). Adding 2t mix oil also lowers the octane of the fuel as well. So, you will be using even less than 50-55 octane, and burning a fuel that runs at higher temperatures. You can try it in a junk saw, if you like. That's your prerogative.
-
Do they have an octane rating? Is it basically 'white gas' or Coleman fuel? Remember, camp stoves do not need high octane - it just needs to burn. It will also lack lead substitutes, as well as any protective additives. It also burns hotter than pump petrol. The Coleman version stateside has this for it's wiki page: Though Coleman fuel has an octane rating of 50 to 55 and a flammability similar to gasoline, it has none of the additives found in modern gasoline and cannot be used as a substitute for gasoline, kerosene or diesel fuel in modern engines. Its high combustion temperature and lack of octane boosting additives like tetraethyllead will destroy engine valves, and its low octane rating would produce knocking.

Hell, I may, too. Getting a car there and back is gonna run me 350 euro included fuel and stena line.
-
I think it would be a good idea as a get together, GTG as we say stateside. I'm not too keen on wagering, but I think it would be cool for us all to meet up and share a beer and some sawing.
-
Eh, she's made more for longer bars. I've mostly ran 066's and 660's in that range. I am told the 394/395's with a bit of tuning run much stronger than 660's. Still, I prefer the 385/390 ported to either.
-
Psh, don't think I've ever even used a 394, let alone ever snedded with one...
-
32 inch bars!
-
I'd be interested. I know I'll be in England October 3rd for sure.
-
Mitch has an interesting vid - including the part where it is closer to 390 Euro in price.
-
When I was making that previous post, in the back of my mind was a little niggle of a memory. It came to front when I was poking around on the webs for something else related. Mitch has a vid of the 562, stock, compared to a few other saw with a 25" bar attached. Here she is:
-
It's true. I can sned a 20 year old cedar twice as fast with a 394xp than with a 362.
-
It has a higher output oiler and they are either cutting pine/fir with skip or it is ported. Once ported, these 562's make a good bit of power. You won't be boxing all day with a 28, but when you need the reach or to fell 20" spruce, it will do the job.
-
From what I have seen, they are otherwise nearly identical. A close friend ran a ported 562 with lathe work not too long ago. He said it was basically a very strong running 70cc saw in practice.
-
The 562XP uses a different pump piston than the 560xp - a bit more output. It will oil a 28" bar. As with the 460R HO oiler, the pump piston ends in a 2 instead of a 1. 560XP: 505200201 VS 562xp: 505200202

I was trying to spell "impulse line" the other day on the phone and all I got was "GOOOOOOOOOOOOOOOOAAAAAAAAAAAAALLLLLLLLLLL!!!!!!!!!!!!!!!" Terribly annoying.
-
I was gonna say - there's likely a reason they are the same...
-
I had an entire bottle of wine for lunch. I'm such an idiot. At least I was passed during the heat of the day here in Lisbon, tho.

I just give the files a good few raps on something to clear the debris from it during filing every few teeth. Seems to keep them from loading up. I get quite a few sharpenings out of my save edges I get from Mackin Rob-D.
