Again, we get the opportunity to keep others in our sites - hearts & prayers that is - while heading into the Christmas season of 2018. Kind of hard to fathom what those that have lost everything from the fires in the West are dealing with on multiple levels, considering many escaped with only the clothes on their backs. Many others did not make it out.
Thinking the verbiage covered my mindset - was a little bit hard to get into appropriate words.
Did not notice too many miss ques on my part with the slammering, so God was smiling on me there.
Qualifier - As mentioned in one of the posts, only two flywheel options. Both the m-tronic and standard coil utilize the same flywheel after a review of the ipl.
Also, the venturi in both the carbs are a little bit larger in diameter than what was mentioned. More like ~ 19.25 and 18.75.
I'm currently available to custom saw modifications. Shoot me an email if you are interested.

Hope this day is finding that you are well.
Nice video I appreciate your humbleness you do a good job. "pray for California", and God bless
Bless you for sharing you years of wisdom with us!!!
When I started watching this video I thought you would just compare the carbs. I didn’t realize you would compare EVERYTHING! I never realized there was so many options.
thank you for your vids. its great to get to see what the saws are for real and hear youre thoughts of them. instead of the "feels good in youre hand" type rewiev
Another great video great to see all the differences between the two saws. Thanks Jack for another great video.
Always informative and to the point brother!!! Stay safe and god bless!🇺🇸
Hey bud, so I witnessed first hand that the newer 661cm have different cases than the older 661s. There are serial breaks but stihl doesn’t specify when they switched to a different case. The newer cases have a piece of case gasket cut out infront of the oil tank. If you use the older gasket the saw will not seal up right and leak bar oil. If you look up complete gasket kits and compare numbers for case gaskets from 661 vs total gasket kit there are differnt numbers. We learned this the hard way
Dave hi.
I think it was ~ Dec '19.
Serial # break is 187601926 ( Thanks to Mike there).
The new version has a "beefed" up gusset on the inside of the oil tank in the bar stud area to add support.
Seems as though some of the West Coast fallers running long bars are knocking the undercut out with the dawgs & cracking the early drive side case ½.
Seems as though some of the West Coast fallers are still breaking the pto side case ½ in the upgraded version.. But, that number has gone down dramatically.
Thanks for the notation about the case gasket set. Similar to the early vs later 066 operation.
Thanks for watching.
Remarkable... Wish I could see #'s for port-lengths on all these jugs but I'm astounded at Stihl's (SEEMING) lack-of R&D on the exhaust-port.....Jennings' work (which is half a century old :P ) says tighter exhaust ports are where manufacturers(racing bikes)were moving, because of tighter exhaust pulses....but chainsaws don't have pipes, I figured that's gotta be why you showed us the 088-->880 exhaust flange becoming -*-significantly-*- larger/megaphone'd....but now, to see this video wherein the 661 flange is now smaller than a 660 flange, unless I'm not understanding Stihl's "chronological numbering system" it means that Stihl made the move to higher-divergence exhaust ports, then *back*....how on earth did the R&D not find&nail "an optima" decades ago? THEN you say the 661 flange is smaller than a 461--- did you mean a 460 or a 461? Because if it's smaller than a same-generation, lower-displacement model's jug then I am just made of questions for their engineers, lol!! BTW off-topic kinda but if you've seen the Grunt Gasket idea (by Dominant Saws) i would be real eager to hear your thoughts, IMO (or 'everything I understand about it') this should only have a positive effect, provided it's not a converging-angle at least IE a choke-point, so long as it's got 1+ angles of increasing divergence it should help, even 1/2 century ago in Jennings' book he mentions Yamaha&Suzuki using at-least 3 increasing angles of divergence on the "entry pipe" that leads-into the divergence cone of an expansion chamber...I always envision our muffs as the chamber, and the exhaust port as "port, header pipe and divergence-cone all in 1" --- having an extra inch of port/header length for more increased-angles of divergence should only help things, it is very very surprising to me seeing Stihl close-down that port so tightly.....but when EPA regulations are part of it our best efforts at "reverse engineer theory" could all be wrong if, say, they intentionally induce a choke-point somewhere....we always operate on them "knowing&doing what is smartest" or at least I do :P
fyi - only 2 flywheels for the 661. arcitc and non arctic.
Redbull661 hi. Yep, it's in the description area. Brain fade...
I did mention from the depths in the beginning. Thanks for watching.
Hello, boss! What do you think about this cylinder gilardoni? They are the same like Mahle , or better?
Great comparison. Thanks!
Hey is there a difference between a magnum far and one which is not like the 661 Magnum and the one which doesn't brand Magnum are they the same saw I'm thinking about buying one but I would really like to know the difference if there is a better one I would like to know thank you
Which of the 661 is better for ripping Lumber
Thank you for the very interesting video. Do you think perhaps there may be a small difference between the anti vibe spring strength between 1/2 and 3/4 wrap handles?
I think I saw there was on my 441 when I renewed them.
Do you like the 661's in general? Folks seem either hot or cold for them.
God bless.
Mr42960 hi. Only one choice for the anti-vibe springs that I know of. Many of the manufacturers used a couple different densities on the rubber mounts and the 372 does have a couple of spring stiffness choices for example as well.
Thanks for watching.
pray for california!
Which carb kit do you recommend? Great video thanks!
I really like the large chip deflector. Where would I purchase one of these for me 661cm? I just now googled “big kids” clutch cover and looked on EBay but to no avail. When it’s spitting chips out they seem to go straight out the back a lot of the chips missing the deflector. Where do I get a larger deflector that is fatter and hangs down further?? Also, where are you purchasing your tachs for your saws?? Hey Thanks in advance. Please don’t stop making videos!
Stephan hi.
I coined the phrase/s "big kid clutch cover" and/or "big kid dawgs". Consequently, you won't be able to find any "Google info".
Any decent saw shop can order you one of the West Coast style clutch covers. If they give you grief, call Madsen's out in Chehalis.
A Google search will net you a place to buy the Pulse tachs. There are several. But, some won't work on the m-tronic or auto-tune saws. So you better verify first.
Dead set on a Pulse that monitors the newer saws, hit the Husky shop. That's who makes their older tachs.
Want a Stihl version, it's the EDT-9.
Thanks for watching.
Thankyou sir
Only thing that hasn't been tried especially on bigger displacement saws is a double wound coil an 2 spark plugs for a more efficient burn ?
Great information video thanks
How hard would it be to put captive nuts on the large side cover?
d hi. The set up is very different. The flange with the threads is long goes inside the 1/2 version cover - which is also wider where the studs pass through. The "bigkid" version cover uses nuts with the thread on the outside of the cover - completely the opposite of the 1/2 style.
A few of the late version 661s are coming with captive nuts on the big kid clutch cover. I'd upgrade it if necessary.
Thanks for watching.
Hi, The new Stihl MS 500i fuel injected saw is about to be released - cant wait to see your analysis on the workings of the saw and how it compares to others. Do you have any initial thoughts on fuel injected saws?
Ben hi. It will be interesting for sure.
I think that the engineers are going the way of the new cars. Partly because of the emission standards. A lot of times the fuel can be "misted" into the throttle body because it comes in under pressure - as apposed to drawn in by the vacuum created from the piston action. Net; more atomization of the fuel and better burn characteristics. So I think the premise is then a more fuel efficient and cleaner running 2-stroke. But then the port timing comes into play along with the scavenging effect - not always the best in some saws.
Thanks for watching.
Will this be a more "stronger" saw versus a carb saw?
Methinks the 500i could be a game-changer ... preliminary findings indicate this version capable of over 8hp+ Along with boat-loads of torque with the correct modifications ... if this proves to be the case it should be a heck of a runner ... at claimed weight of 6.3kg (13.9lbs) it’s not much heavier than its little brother the 462c at 6. 0kg (13.2lbs) ... anyone wanna buy a ported 395xp lol
How does a ported 462c-m compare to the stock 661c-m?
Jesse G hi.
I guess it would depend upon how far a guy went with the porting procedure on the 462. It would also depend upon the condition of the 661.
I posted a video back in February of my 462, a 572, and a low hour, stock 660.
The 462 was about a second, second and a half behind the 660.
The newer 660s and 661s run about the same. Some of the older 066s run a little better than the 661s.
I will be posting a build series with an 066 vs. a 661 shortly showing that.
Thanks for watching.
Ohhhh mannn... I was hoping to see my saw on the bench.. 😉😉😉😳😳😳
Tj hi. Your saw is sitting ~ 8" to the right of the screen edge.
Thanks for watching.
hotsaws101 hahahahaha yessssss. Thank you jack ... I can’t wait to get it back and cut something... god bless
so the handle molding is the same on both interchangeable?
I have the MS 661, what are the adjustments for the H/L and then the Idle. I screwed both H/L clockwise to seat. Then the H screw I turned counterclockwise 1 1/2 turns and the L screw I turned counterclockwise 1 turn. The idle I seated it and then turned it counterclockwise 3 turns to get a feel for it. BUT I can’t get it to stay running for more than 2-3 seconds. Any suggestions would be more than helpful. 🙏🙏🙏
KC hi.
Stihl sometimes has the setting on a sticker, or impregnated into the plastic on the side near the needle guide.
Don't remember seeing one of those on a 661. But, I'm not looking for them either.
It is usually around 1 or 1¼ of a turn out. But, that saw has limiter caps on the needles. You get around ⅞ of a turn, but not usually from being bottomed.
I'd make sure the throttle shutter is open far enough so the saw will idle.
Then you can adjust the low to where it needs to be. At that point, you can dial in the high speed needle.
Where the needles end up will be different for a guy at 500' and someone else at 5000'.
Air density, and the associated water vapor content plays a roll in where the needles end up additionally.
Air cleaner choice and how dirty the air cleaner is will also slightly affect the needle adjustment.
Therefore, there is no adjust them to "x" position.
I did post a video around 4 winters ago that has the way I adjust a carb.
Best of luck.
Thanks for watching.
@@hotsaws101 I truly appreciate your feedback. Thank you very much 😊🙏
So what's the name or part number for the non mtronic kit, if anyone knows. Thanks
So big question, can you convert the mtronic to standard by swapping parts?
Corey hi. Yes. They make a kit. SUPER spendy operation though.
Thanks for watching.
Hi I teased you a little at first but I know your the real deal .I have a request for a video I'd like to ask of you. I'm 70yrs old but still use a chain saw daily in the winter .I usted to lose my bar cover often in the brush 1 day for fun after cutting a dead cotten wood tree in my way I plunged my bar in the base all the way the cut the plunge cut out on all 4 sides then the end an had a neat bar cover again 😁I doubt I would have enough control to do it now but bet you could an would love to see you do it on a video ?
So this comparison, the "real" difference is standard adjustments vs the M-tronic?
Michael hi. Coil and carb for the most part. A few other minor features. Thanks for watching.
@@hotsaws101 Thanks. Is the Mtronic capable of self adjusting to any porting and other engine work? I'm thinking old school car tuners tweaking jets and needles in carbs vs new-age tuners "just plug the laptop in and tweak this value here, that one there".
What is the part # for the single blade coil?
any thoughts on the new stihl fuel injected saw?
Jack on m-tronic saws is a way to do away with limited coils
Nick hi. All? Not that I know of. Some, yes. th-cam.com/video/bxXz75m8PiU/w-d-xo.html
Thanks for watching.
Why plug the decompression valve? For performance or to prevent leaks or other issues? Can anyone answer thism
Sully572 hi.
Every once and awhile the head will break off. That's a costly endeavor on a zipped saw.
Thanks for watching.
@@hotsaws101 thanks....kind of what I thought after reading about valve's falling into the cylinder. I think my saw came from logger in Oregon, so makes sense. THANKS for replying and I am looking for a saw to have you make a good logging saw out of too.
any chance got any leads on getting a 500i sent your way when available??
Well, I guess anything is possible. If God is smiling on me, then yes. Christmas is on the horizon.
Thanks for watching.
How do I get in contact with you to see about getting a saw modified
My contact info is in the description area - thanks for watching.
Can we transform a 261-cm into à 261 as I am so disapointed .
Luc hi.
I haven't looked at it that closely just yet. I do happen to have one of those coming in shortly. Guess I'll check it out at some point. Thanks for watching.
@@hotsaws101 m'y dealer seems blind by the technologie in the 261 -cm ... but will look at à too soft spring for an air valve on top of carburator thanks
guy in my area has a new 660 and and a 661 what is the better saw ?
d pete hi. I guess that depends on what a guy is looking for. The 066/660s are a proven platform and are fairly bullet proof. The 661s had some electronic and over heating issues early on. The fuel metering solenoids are prone to malfunction and only cost (the part itself) ~ 45 to replace...
Occasionally the coils still go out it seems. I think that it is possible to get more lowend out of the 661s IF using all stock and original fitment components for each saw.
Thanks for watching.
@@hotsaws101 thanks for the reply.i went with the 660 think i will just put a muffler on it and maybe max flow air cleaner. looking forward to more of your vids thumbs up
Where can you pic up a standard 661?
Jeremiah hi. A foreign country that sells the standard I "wood" imagine. This one came from a client. Thanks for watching.
@@hotsaws101 makes since. Id like to get my hands on one.
Good Morning! I have a MS661 that I would like some work on how could I get in contact with you if you’re taking new customers right now ?
Thanks
Elliott Kirkman hi. My contact info is in the description area. Thanks for watching.
OH to the real geeks who also happen to work in this kinda stuff (or anything where you can use headphones [some of]the time you're on-job), please watch-through the video so people get the Views for it but you can just rip/download the audio only (I use youtube-dl, audio command would be `youtube-dl --extract-audio --audio-format mp3 [url here]`) and voila you can take some of these long dialogues with you, I know audio-only isn't the full experience but you'd be shocked just how much you get I mean well over 3/4ths of the point is obtained verbally/by his description, not by quick glances at the camera -- obviously you can only spend so long at the PC actually *watching* this kinda content but MP3 lets you kill half a dozen vids on 1 job >;D
I like m-tronic. Yes u can't a just adjust the carb urself. I porting a poulan pro s25. U have to take cover off to adjust carb. So on saws like that. Ur going b adjusting carb every time weather changes to have running a peak. So it kinda agrervating.
How bout that muffler cross over 2 660 066
Jared hi. Not a direct bolt up situation. Pretty much impossible with a 60/066 can. Thanks for watching.
@@hotsaws101 well thank s you have your hands in lot more than me so thank u and if u have some tips buck em my way
So... Stay ported 660 066💪😉
Jared hi. Yah maybe. But then a guy has to have enough extra 660s under his bench to last until his retirement....
A good zipp-able 660 is getting scarce. Thanks for watching.
@@hotsaws101 well stihl is the best at lasting I'm stihl running my 044 10 pin as my work horse it was old when i got it i buy other people s basket cases n port then fix i luv it
Yeppers ... I’m scooping up all the 461 , 064 and 660s I can ...better to have and not need ... than to need and not have !
I'll skip were the current line's well ish, i have new small n. I'll go from carb to fuel injection but skip the 1980's cars, u know😅
Well electric choke falled in motorcycle' s moped's. So i got opinions and to use it to adjust load table s n what not. I'll try to wait little longer(500i)just hope the programing isn't gona be too pricey but probably but cant wait to see it go that way
is it me or does this guys voice go UP every 7 words?
😂👍yep more like every 4 words
Who do you know in paradise? That's my hometown and I know just about everybody that logs or bad a ported saw up there
Kyle hi. The two guys I references were not involved in the timber industry. One was an arborist type guy. I have not talked to the third guy that works in and around the woods it seems. Probably would not be appropriate for me to mention names at this point. Thanks for watching.
