Great video mate. I’ve been singing the praises of these ugly little macs for years. Simple, tough & reliable. 👍🏼

Just blew mine up and I'm way more bummed about it than I probably should be. My old 610 could do mill work, landscaping jobs, and firewood cutting just as well as my modern saws, but it had that cool factor and honestly fit me better than almost any saw I've used with a 26 inch bar and skip chain. Yes it's a McBrick and it's annoying to repair, but it was MY McBrick. As a guy who grew up in the Pacific Northwest who knows big trees and good saws - Don't overlook this machine.

I just did a restoration on a 650! it looks like new now, and runs so good I was about to cry. LEGENDS NEVER DIE

Purchased two 610 at sears back in the 90’s used the daylights out of them and stored them for over 20 years. Decided to see whats up and see if they still ran. Changed fuel lines that crumbled and they fired right up. Just replaced 20” bar with a new 28” bar and ran stihl 93 octane pre mixed fuel. Screaming cutting wood spitting sawdust 15’ away. Totally a badass saw. Heavy as hell but badass saw. Appreciate the video💯

Thanks for the great history lesson on the 600 series, you've answered a lot of questions I've had! Keep up the awesome work 👍👍💪💪😁😎🇺🇸!

Was recently given a 610. Going to get it up and running for bucking firewood.

I have one that was left at shop, new jug kit and it’s a good saw and I also use poulan saws also 😊

They are great to buy on the cheap even without trying them out because they are so incredibly reliable. If the saw is not totally beat up, you can be pretty sure it will run. And if they do need repaired, parts are available. And they are easy to work on. What's not to love?! Thanks for a great video.

greetings from germany, i like that saws too

Great video Sir, I just got myself a 610,, and can wait to bring it on the field, thanks for the information.

Good series overview, Mr. Mac!

Thanks Bryan. The 610 I got for free from my brother-in-law runs fantastic after I replaced the diagram. I am going to put a 28” on it with a skip tooth on it. This was great information for me and may others I am sure.

Bar oil fill is a pain but love my saw. 40 some years old and still running strong with very little maintenance.

I have 2 610s. I had 28" bars modifyed for then & they cut just fine&dandy Bryan!

Just purchased a 610 and 650 pro Mach and bought a eager beaver 3.7 about a year or so ago the 610 and 650 are running good still working on the eager beaver tho great video

I love the look!! Now when they first came out, I can see folks funning on them. However, this is one of the "MADE IN USA" vintage models. It's a rare jem these days, and they are easy to fix. Treated properly, this sucker will last a life time or two. I have my father's saw from the 80s. Still runs like a champ. I just had to replace fuel lines and a carb rebuild kit. It's a time machine too if you want.... It's 1982 and Ronald Reagan is president!!!!!!!!!!! :) Thank you my friend!!

I have a 320 that I'm putting back together from a box of parts and have a 610 coming from ebay. The 600 series is literally the big brother of the 300 series. My dad has a 310 and I like it alot. I got the 320 for parts then decided to make it a running saw.

Got a free 1974 or 78 (the sticker on it is not very definitive) 310 that hadn't ran in atleast 10 years, maybe even longer. Yet with just taking the plug out, oiling the cylinder and chucking some fuel into the carb it ran. Hell i found out today that the diaphram still pumped fuel. its insanely loud and smokes so much that it deters mosquitoes and other people in a 2 mile radius and i love it lol

Awesome review.Thanks

Last 610 I got I paid $25 cause the guy said it wouldn't turn over. The recoil was all bound up. Shortened rope and put back together, fresh fuel and running.

My Dad had a McCullough 610 Pro Mac that he purchased in 1979 (I believe), & he really liked it. I inherited the saw, & used it some. I thought it was a well engineered saw, & in some ways, even by today's standards (smooth & quiet power). I decided to sell the saw after I learned McCullough had gone out of business, thinking parts would become hard to find (due to no more organized parts support). This turned out to be basically true, & at the time I sold the saw, I hadn't yet done much online parts shopping, but mostly obtained parts from a local small engine shop. Now, there may be some online sellers that have either NOS or used parts for these saws. But I didn't much want to sell the saw, as it ran very well, & was in excellent condition (I took good care of it). Anyway, thanks for the infomative video on the McCullough 610 chainsaws! Cheers

Thank you for posting this! I am rebuilding a 605 right now! There are videos over on my channel if you are interested. I have never worked on a diaphragm oiling saw. I learned several things here!

Great video Bryan. I have a few of the 600 series saws (610, 650 and 655 versions and a 5700-20). They did come with a tillotson carby as well. I like the 655 saw it runs much better than the 650 and 610 versions.

They are great i collected some of each; 605. eager beaver 3.7, and 650s. they always run and are rock solid dependable; more than stihl saws i have owned.

Great video!

Great video

About a year-and-a-half ago I picked a 610 Pro Mac up for $30. I spotted it on OfferUp, the guy who owned it literally used it I think maybe twice and just put it away in the garage and there it sat for years. All I had to do was replace the fuel lines and I basically now have a brand-new 610 Pro Mac... even the original chain was still razor sharp. Definitely a lucky find.

Thanks for the video. I just got a "barn find" 650 Pro max bow saw (all metal) The guy was cleaning out and told his helper to go throw it in the scrap pile. So, now its in my barn.lol. Yes, compression feels good and bar and chain in good shape. Will mess with it one day .

If you think about it I think the design of them was similar to 041,051,075 Stihls. Very similar but with McCulloch twists to them

Great channel!!!

Hi Bryan!!😀😀 Old Mr. Obsolete has a huge collection of saws and he just loves the 610. He uses it for blocking a good deal of his firewood. Take care my friend!! Logger Al

I started out with the mini mac my very first saw loved it so much i just had to get a bigger MAC so i got the pro mac 610 from JCPenney back in the 1980's , the 610 has sat in the shed in its case for way over 30 years well two days ago i pulled it out fueled it up and put bar oil in, primed it put the choke on and around the 5 -7th pull it pop i took the choke off and primed again this time it fired right UP idle and ran Great everthing is working just fine Unbelievable ... McCulloch are Incredible Saws...

I just had a used 610 given to me, best chainsaw I've ever owned.

Just got one for free and it appears it didn’t have a tank of gas ran through it!! Looks brand new even inside the muffler Guards in the clutch area shined and new with no nicks And bar is mint Had lots of questions about these saws and you’ve answered most Thanks fir making this video Now I just need a brown bag to put over it so I can look at it in my shop It’s uglier than pooting in church

Mac Cinderblock...that's a good one....worked in the woods 44 years never heard that one before...Shoe in SW Oregon

Love the Mac history. I’m putting together a book of specs on the saws I’ve got. I just can’t pull the trigger on these 4-800 dollar saws! I started chasing the carb kits for the 250…but they all have an “HI” suffix. Call me stupid but, does the HI make any difference? Just want to make sure I get the right kit. Thanks…lovin the channel!

Wondering if anybody knew how to adjust that high idle lever,,, mine doesn't work anymore,, it's the only problem I've ever had with it,,, it doesn't affect the idle anymore,,, it's never been apart and if I grab it when it's set to high idle and pull it'll raise the idle somewhat so it's still connected but it doesn't work properly like it once did... Anybody have a diagram so I can adjust that and repair it,, thanks !

Nice video Bryan!

Have one finally died couple years ago was debating fixing the ol pm610 but after porting my old stihls 038 mag don't think I'll ever fix the 610 lol, was a good torque saw

Mines a Montgomery Ward. Posted on my channel. Actually felt good running it.

I got a timberbear sucker rips through huge logs

I take the chain brake handle on all my saws and cut all that crap off and just have a straight handle ( like a gear shift) on them . Simplifys things , atleast for me it does.

Bryan you are helping the Mac world grow for sure. Great work buddy. I am wondering if Mcculloch made any of the 10 series saws with an exhaust port without a divider in it. Thank you not sure what this saw is but it looks factory. It's a bit of a different style cylinder.🌲❤🌲🪓✊

I think you just answered why my new oiler on my 650 won't pump itself. It will oil manually but no auto oil.

I always said these saws were ugly, and I still think so. But the way you look at them and describe it I'm kind of looking at it a different way now. I'm glad it never threw them in the sale pile. I have a few. Thanks Bryan

I have a McCulloch Pro Mac 610. I've watched one of your videos where you rebuilt on 610. How do you pressure test this saw without the mcculloch intake port adapter (p/n 94415)?

Love seeing that 125 cut music to my ears.

hi bryan im wondering if you can tell me from the book how t diagnose the oiler not working. the manual primer works but not the auto feed. thanks again brother!

Hi. I just caught your video. I have a Montgomery Ward 24084a, which I believe is a Mac 610. I got it running, replaced the rope. It runs really well, but when I start to cut in a piece of wood, the chain looses momentum and quits. The engine doesn't bog or cut out. What could be the problem? I cleaned the clutch and drum with brake parts cleaner. Is there a measurement to check, between the clutch drum and shoes? It has a 20" bar. Thanks for any insight.

Quiet, yeah right! Those mufflers are essentially straight pipes. Got 4 of these, 2 will run, 2 no spark. They're great saws but using a 28" bar, no way but a 24" does work good. All of mine have 20" bars & I've used a 24" on 1 years ago. As you said the oiler diaphragm can be a problem & I've never been able to find 1 since McCulloch went out of business. There's a guy, recently deceased, that had a lot of MC parts not far from here that likely did have parts but no idea.

I run a 24" on my 650

Bryan, just asking for your educated opinion, but for the 55cc Bear. Is it worth it to pay $150 for an excellent like new one with the original 20" bar. Enjoyed your video, answered alot of my questions. So, I became a new subcriber.

Yeah I think I have at least two of the 610's not the 650 that have not ran in twenty years plus , I would be a happy camper to get one of them up and running

Can someone tell me what kind of spark plug I need for a PM 650

What can the 610 cut in size w 20 bar? Also in comparison to a Stihl 360 is it more hp ?

I got one just needed a spark plug and a new rope

Question for you. Have you done a video or have you had any experiences with the Power Mac 300 series. 310, 320, etc.? I have my grandpas 310, and I was wondering if you knew any of the goods and bads on them.

I got a in parts McCullough eager beaver 2016. Put together again with new oil and fuel lines. Sounds good running. I need a bar and chain. I'm finding replacement bars dont fit. Any suggestions?

I got a McCulloch 605 and Montgomery Ward power Kraft version

I've got a Timber Bear I bought off a crackhead on craigslist. I changed out all the fuel and oil lines, and put a new bar and chain on it. It runs pretty good, but when I got it it leaked fuel from the gas cap if you tilted it in any direction. So I put an O ring in the cap to stop the leak. Now it'll run till the motor puts the tank under vacuum and dies. So where is the vent for the tank supposed to be?

Ive used vintage homelights for 5 decades. Today I bought a 610 for $20 its very dirty and gummed up The owner has never gleaned it. I partially disassmbled it and sprayed it with cleaner. maby I can bring it back to life?

is there somewhere to get parts for the vu sa??

Have any experience with the pro mac 5700? Just bought one its the 57cc version. Can’t find much about it

Do you use 40:1 oil or synthetic all ratio mix? I have used synthetic mix in my newer 2 cycle saw, tiller, and trimmers for years. I have not owned an older saw that called for 40 or 20:1 gas.

My 610 has a tioletson

MISTER MAC GRAY!!!! 🖤💛🖤💛🖤💛

What makes them so popular is the 10 series saws and buckin billy ray and the internet the 1010 saws are going thru the roof on prices but these plastic blocks are still cheap but basically the same saw

are chains and bars easy to find for these??

They also made them into cut off saws👊

Hi ! Jostein Norway here. Thx for demo and well I just also got me a 610 here ! :-) Can you help me with 2-10 I got here. Not familiar with Mcculloch... you know...most swedish here he he. On the 2-10 the is sprocket...looks old and maybe original...from start he he of saw. I can bearly read 62572-A on it and other side...SM 57. Do you know if it is 404 pitch ? Where to find chain and bar for that sprocket and that saw ? You know ? It har a bullfrog in it and i got it running he he but cant wait to get chain and bar...that i can use. We more used to 3/8 and 325...which seems not to fit. It looks like 7 grip or teeth... It is the round type spriocket... not the star kind of theet lokking sprocket...if you understand what i mean. Ansvers apreciated !

I have a pro mac 610 just need the proper carburetor settings

Is it my phone or is the volume all shotty on this video

The timber bears are 58cc. The cylinders will interchange on the 600 series

I need pull rope full assembly for my saw

Great video. I picked up a timberbear at auction for $20.00. Gassed it up and it runs great. It was even sharp. Picked up a real nice super pro mac 610. Next thing to nos. Looks like it cut one branch and was stored. Not even a scratch in the bar. They definitely live up to the Mcbrick name, 610 with 20" bar weighs almost as much as my super pro 81 with a 28" bar.

Love the manual…cheapest I could find…200 bucks!! 😮

In fact l need a starter for 1 of my 610s...ya got 1?

My automatic oiler does not work but manual does

Saw the 3d printer hiding in there... you print up any saw parts?

Wut really sucks is when the pull rope hangs a bit long and your holding the saw with both hands and cut off the saw. It recoils the length of rope 9 out of 10 it's gonna hit you in your family jewels.

Send me link to your oil line repair plz

Just grabbed one in pretty good shape for free that someone put out at the curb, with the case! 😎

BRYAN I HAD A 610 FOR A LONG TIME, BUT IT WAS SO HARD TO GET THE CHAIN OFF AND IT WAS HEAVY

You forgot to mention the eager beaver 3.7 it’s also part of the 600 series

How is the zama any worse than the zama,

..Buckin' Billy Ray Smith is a big part of the reason McCulloch chainsaws have been getting more popular... :)

Buckin billy ray.

The McCrysler or the McTauraus......

Because nobody wants to give up there 850s😁

Haha yep non to pretty looking but seem to be great saws from what everybody says.

One day these are worth $25-$50 ......the next they're going for $300.

610s are one of the ugliest saws ever made. But one of the most reliable I’m about to go get a pro mac 610 with a 16” bar for 35$ it runs ( feb 19 2021)

Who you teasen! That turd ain't worth the time it takes to light it on fire! I had two of them and both were hard starting heavy and they don't look cool!I have a chainsaw collection of around 60saws,And there's ten macs in there,Not one of those ugly bastards to be seen!
