Spring AV?
Title: Re: 661
Post by: jmester on November 04, 2013, 07:22:08 pm
yes. i was not a big fan on the av springs at first but my 261 changed my opinion about that.  looks to be m-tronic as the only option.
Title: Re: 661
Post by: jmester on November 04, 2013, 07:31:44 pm
looks like it also lost .5 cc in displacement and pick up .3 in bhp over the 660.

661 is Stihl's first big cube saw in spring av , air injection and micro processor control.
241CM- 661CM......Husky has a lot of catching up to do now ;)

Post by: mdavlee . on November 04, 2013, 08:06:44 pm
It should be a good runner with the cylinder setup like the 461. It doesn't have a double barrel strato carb like the 441.

I was hoping to have a non m tronic first. But I guess we will have to take what they give us.  If it runs any thing like the way a 261 runs it will be hard to beat. IMO.

I'm eager to buy a 661CM. My 395XP is getting real old school to me now ;). From what I have heard about Husky and Stihl sharing this so called micro processor technology, I think Stihl got the better deal. :D
I still don't see a big cube AutoTune saw in Husky trim in the near future. :'(

I was looking at my part look up today, and saw that they increased the bore size to 56mm.  I think it is going to be a good saw and who knows maybe my first micro processor saw. Don't worry they will all be auto tune or m tronic before long then fuel injected would be my guess.

Yes fuel injection when they introduce it will change everything.

Yeah there are probably many out being tested for the last few years if not decades. Stihl already has a large cut quick saw TS500i in their line up for a few years now with fuel injection.

Quote from: Saw Dr.
I just came back today from a couple days in VA beach at the factory.  I was able to talk to a guy who works with field testing new designs.  The 661 will be M-Tronic for the US market, and apparently the M-Tronic on it will have more control authority than previous versions.  There is also a vertical spring on the front of the A/V system to support when long bars are used.  They would not let me play with one   :-[

Big changes also in the works for the 201, and it sounds like the new stuff for it will be "backwards compatible"

Tuesday morning we will know , hope its not pouring outside . From listening to it when he has been blocking big firewood it sounds like its got pretty good rpms in the wood and holds them good, Pete wants to try the 661 against his ported 372xt and see how it holds up

Since they started selling the stihl ms661 again this week. Brad bought one and got some good pics.

nope, I'm about an hour away from him right now logging , he is coming by early next week, I got a 088 here he wants to use in his mill  . But from listening to videos of how their 661 runs I can sure tell you that Pete's 661 is alot more rpms than the others I seen video on and its sounds like the carb is jetted pretty close , he likes it . But he is to bring his 661 and we will see how it runs

I bet you = 45-70

Now you might know more on this to help me. I have always liked the .444 after shooting one in lever action many years ago.  What would be  gained anything or lost to 45-70?   We allow these for gun season now is why I ask.

Post by: Eccentric on January 01, 2015, 04:13:26 pm
More heavy bullet options in the .45/70.  More powerful 'standard loadings' (found in 'regular stores') in .444.  The regular Winchester/Federal/Remington .45/70 loads are low pressure, so that idiots don't blow up great-grandpa's trapdoor springfield with 'em.  Specialty loads from Garrett and others more closely approach the power that you can get from a strong modern .45/70 with handloads. 

On a related note..............that was the reason for the .450 Marlin.  It was a factory round that basically matched .45/70 handloads that were appropriate for the modern lever guns........................with the added benefit (from a liability standpoint) that it could not be loaded (by morons) into old rifles that couldn't handle the pressure.  It's basically a 'legitimized' .458 American wildcat, but with a super thick belt so that morons couldn't load it into rifles chambered for long (but smaller caliber) belted magnums such as a .300 Weatherby (big boom would ensue).

Post by: EHP on January 01, 2015, 04:23:46 pm
I got a big field full of pretty nice big timber still in tree length , once I get finished pulling everything out the 661 and the 390 husky are going to be put to work for a couple long hard days of bucking up . I still got about 40,000 to 50,000 more feet to pull to this field and let the bidding wars begin on the timber
Title: Re: stihl 661
Post by: Old Iron Logging on January 01, 2015, 04:24:14 pm
Factory loads to 100 yards the .444 is better. Wish I still had my .444.  Hand loads tip things in favor of the 45-70. Better bullet choice also for 45-70. Long range the 45-70 wins hands down. Some of the Sharps replicas are great shooters.

Deer season here starts in Sept. First two weeks bow only. Muzzle loader/crossbow starts 3rd week of Sept to middle of Dec. Rifle season last weekend Oct to Dec 6.

2 tags, rifle only and bow/ muzzle loader.
Had a single shot 45-70 years ago. Want another.

Use a chainsaw for 3 cords of wood per year now and my 241 will handle that. Still have 10 saws, but can never have enough guns.

the 661 has more power than the 660 plain and simple , compared to my 066 I'm not sure on that but this 661 is not broken in yet so once that happens we will see , I would use the 661 to fall with in this bigger timber on these steep side hills but my ported 365 works so nice I donot want to use or carry the 661 for that job , maybe once ported I will change my mind but at this point I say no and run the 365

Yeah they're not impressive stock. The 385 and 390 run almost identical stock. There's 390 was 16 lb 12 Oz or something real close. Nmurph has a weight for one. 

A good ported one is more impressive than a 660 to me.

I have been using the 365/372 xt saws for cutting timber . I got a 36 inch setup right now on my 372 xt that I cut a bigger walnut with and have more to cut of them the beginning of the week

Still like to know how the old 066 compare to the 661 stock for stock. But finding a good stock 066 might be hard. 

I had a NOS no decomp cylinder and know where it is today. But the crankcase was updated to a poly with ported non decomp topend on it too.

I would think a 40mm stroke would be advantage over the 37mm stroke in my mind.  The poor stock porting in the 660 handicap the saws IMO.

Your take on this with the 3mm stroke difference. I know I like longer stroke motors.

My friend has a 661 and a red eye 066. 661 is faster. Real close to my ported 064. For a commercial guy no doubt the 661 is better for fuel economy, antivibe, and puts the smack down on a 660.

I have not had my 066 that I use to cut and race in stock class for a while but I'm pretty sure it would out cut this 661 , That 066 was dam strong and fast . This 661 runs pretty good , has lots of torque but my ported 372 xpg is stronger and faster even with a 36 inch bar setup , the longer the bar the better the 372 runs and pulls a head of the 661

I know my OE ported 375 could cut with my ported 066 with 32" or 16"  Both IMO were top of the game back in their day.

Never got to time the 32's to see how close or not they were.

There's videos from Australia of a 390, 660, and 661 ported in the same wood. 40:1 and 50:1 test thread

cannot learn much from those videos, just the way the saws were run its hard to tell how they can cut

Yeah the 390 was a bit rich and the 660 way rich.

Thanks Kevin, one thing with the 661 if your doing a video is make at least a couple cookie cuts then do your video , the 661 will run rich until it leans itself out

I find my 661 takes up to 5 or so cuts before its sets itself proper , the video I did of my 661 is all that saw has in it , that was a new chain but I filed it to make it cut a faster time and cut the rackers as well to help its time , If I had just ran the new stihl chain the time was 21 sec.

Saving from CRG today.  =  The early plate saws would pull the plating off during the first 20 hours as they broke in a Gilardoni cylinder. They started coating the pistons in Tin to help with scuffing from SN:181912016 during break in. They switched to the casting plant in Brazil in 2017 , those cylinders have STIHL BR on them and have a different port geometry to keep from pulling the rings off the piston.

 186691003 is the cut off between Gilardoni and BR. You could still pull plating after break in. That cylinder also looks like it may be a dud. The transfers are awfully sharp too. Do you have any bluing around the rod bearing ? You can start to get rod failure and pull plating also. That's not a cylinder that inspires confidence.

 I'd be interested to see how many hours it truly had. I know from 184316xxx back they had a two piece crank and changed to a three piece crank that helped keep rod failure down. Good luck on a cylinder I've been on backorder for 1 month with 3 of them.
