It doesnt. Redbull is using a new chain for each test. Less ratios tested equals less chain used

Ah OK. Now I see a lot of were prefeing to use the .404 over the 3/8 chain why is that? Doesn't the .404 take more power to turn?
Stays sharp longer and is a bigger tooth which lasts longer overall. Not much difference really. I'm going to try a 32" full skip 404 on my 044 tomorrow.

Ah OK. I'm not a professional tree person/logger. So I'll stick with the 3/8 chain.
While I found Brad's 661 to be a fine saw with ample power, great AV and Stihl's always great build quality. The Mtronic system leaves much to be desired in tuning consistency. It would be tha last saw I'd use for any type of fuel testing IMHO.

I have a ported 395xp with 36" bar right now but gonna put a 42" on it. Where I live we have big trees to cut. I didn't fall this one but is one.left over from a logged area. Its at least 5' at the cut area.

I think it will be fine. It's only that occasional stumble off idle. That wouldn't affect this testing at all. It will be key that he makes a couple cuts to get it up to temperature because it does run a little rich the first couple cuts. After that, I find it to be very consistent.

We have a long deer season. Oct.1st to mid-Jan. Early Oct. is bow and primitive weapon. Late Oct. starts modern/regular gun. Dog running is allowed first week of December. We're allowed to harvest six per season.
That's fine, but I totally disagree. Again the 661 is a fine saw, however the tuning seemed a bit erratic at times, and IMHO that's what is causing some the stumbling problems. Obviously these saws have issues to some extent, therefore they simply cannot be relied on. Any testing done that requires constancy and repeatability will be impossible with that saw. Why use a saw model that has know problems? That makes no sense, unless the person performing the test can't tune a saw properly, which is what I'm guessing. I mean I wouldn't rely on a 562 for the same reason.

Not sure about the 661, but my 562 has always been spot on. Never bogged or ran anything but perfectly.
Mostly referring to the early production runs. I ran a few that were total dogs. I also thought you said the 661 was a mess. At least that's what I remember you saying, I could be wrong.
I would ask if the system works so well, why is Brad and others, looking to run a normal carb on the 661?[emoji9] Again the 661 I ran was very stout, had a great feel, build quality and so on. But I'm not sure about it's fuel management system.
I call it as I see it.

I ran my third NIB 661 today. Performed perfectly. Actually ran both a NIB 390 as well. Hands down the 661 all the way.
At the end of the day I asked myself why did I buy this all orange turd compared to the 661, other than it will be visiting Cincinnati in time.
The 562xp and 550xp are great saws. Can't wait for both the 70 and 90cc Husky replacements. Standing orders for when they hit.
The ported 365xt ran right with the 390, however it is broken in and turning 14700 now. No guts no glory. I even re-tuned and ran a tank of 58:1 just for fun. Xtorques like to run on the lean side I've found. Another good running saw.
Until you own a 661 and have put days of hard work on one really can a tank or two be any kind of assessment? But then again this is AS site lol.

I know a lot of us are brand specific. And I see a lot of people bashing huskys cause they aren't running electronic carbs on there bigger saws. But I've read a lot of people saying the new 661 has idle and stumbling problems off idle. But on all my carbed huskys I've never had that issue unless I had a dirty carb from sitting to long. Now I'm not a logger or tree cutter I'm just a weekend wood cutter. So there for I'm always cutting wood in the same altitude ranging from 5800-7000'. So my carbed saws don't run any different that I can tell between the elevations.

Is the 390 ported?

How can you compare two differnt size stock saw to one another? There is almost 4cc difference between them. The 390xp is smaller saw. You need to Compare it to a new 395xp to make a fair comparison.

Oh ya. That 390 has to be ported but I know the 661 is strong even stock

4 cc. Well I'll be. You are right. But I didn't want a 395xp. Then it would be to the Husky advantage by a couple of cc with a 395 and that extra weight don't interest me. Brad's 390s run great once he gets done with them. That was the purpose of the buy.
Just wait till the 390's replacement gets here. That should be one very nice saw.

Also the stock 390xp has 6.3hp compared to 7.2hp with 661cm. Son you have almost 1hp difference as well.
