My father gave me his Pro Mac 610 back in 2005 that he used in the 80s in upstate NY on our farm when I was a kid. It still runs great, I have always loved the look and sound of it. It makes me think of my dad and I working together, he would cut the wood, and I would pick up the pieces and stack them in the wood trailer behind the old tractor. I have all the manuals, parts, owner and service manuals for this series. In 2006, I got one of these used saws on eBay for $50.00. Sold as is, not running but has good compression. I replaced the spark plug and it fired right up. I kept finding these saw for dirt cheap on eBay so I learned how to repair them, which isn't that hard. When I moved from New Mexico back up to upstate New York in 2020, you should have seen the look on the faces of the movers of the Atlas moving company when they were in my shop looking up at 13 McCulloch Pro Mac 610s on the shelf, then the vintage 10-10, 200 and 250, Model 15, Mini-Mac, Homelite XL Automatic, Poulan Pro 4218a, and two chinese chainsaws (58cc and 62cc, one orange and the other yellow. That's when I thought to myself...."What the hell is the matter with me???" LOL Thanks for the video!!

..Torque, man, torque!..slower RPM's, but way more grunt than a newer high-RPM saw, especially in a similar displacement situation...I love it, an older guy(I'm 55 myself) that say's your a weenie if you complain about the weight!.. :)..I'm a long-time chainsaw mechanic, but have pretty much retired from it because I have had enough of the modern autotune, m-tronic, strato saws, etc. with finicky electronics, extra wires, complicated intake systems, and extra crap crammed in there that make them difficult and time-consuming to work on...I get guys all the time, who keep wanting a lighter and lighter saw(but want the same durability and power, of course)...often, the older the guys are, the lighter they want their saws..well, I hate to say it, but when you start complaining that a 10-pound saw is too heavy, maybe you're getting to the point where it's no longer safe for you to run a chainsaw?....

Hope you have a good week buddy they all cut great love e thanks for sharing em with us.

I love these old saws love to work on them too. Nice collection

Thanks you two! great as always, really look forward to your video's ! regards alan.

Saw therapy as I call it!! Nice collection of McCulloch saws!

just got my dad's old 5700 running today great saw hadn't ran in 20 years

Thanks for taking the time to make this sir. Very informative. Appreciate it!

Great overview of a SOLID line of power saws. I have a 610 and agree with everything you said about these saws. Great video!

Good imformation!!!

Great video. I love the 600 series saws too. It’s not about being the lightest or fastest cutting, it’s about being super reliable and these saws are.

So I decided to get new bars for my 610, and Montgomery Ward. Then both coils failed in a week. Back to the '87' Jonsered, but she now tinkles fuel when full! Ah well, winter is here, no cut'in icicles for me ! I must say you do a fine grind to the chains. THANKS MUCH

OK, you've got me! The 650 is on my wish list now! 🙂 I'm a 10-Series / Super Pro guy so far. Very interesting information about the factory porting of the 650! Here in Germany there are a few 600-Series saws on ebay from time to time. Most of the times around $70 to $100. The are no real beauties in my eyes, but let's see how it feels having one of them in the woods. It sounds to me, that they did some very interesting improvements in comparison to the PM 10-10 for example, with the anti-vibration and adjustable carb and oiler from the outside. I have a PM 300 which is crap to me and I always thought that the 610 and 650 play in the same league, but you made me curious now. Let's see! 🙂 Thank you for your informative videos! Kind regards!

Hey ! Nice one...and like you humor or the frases..." common like dirt but rear as heck " he he. I have a 610 and so positive to hear all this positive about exactely the saw i bought on trip home...witj out knowing much about it. Those might be the most produced volum saw...but one told me that S-10 Stihl was the biggest in the volum on planet ever... I hear you say Homelite is it...? 12 is good number second with not so big margines. ANYWAY....the saw ...the 610...it is rear i will say here in Norway...to be bought and found...so I very happy owner. Yes...it started right away...but waiting for a fresh chain...as it was very dull. Of course make clip/ film of it later on... Thx for informing us and sharing ! :-) Not many of you kind with this level of interesting insight !

Really cool

I picked up a vintage 650 and two 1-40. They are low RPM but all still running and still cutting through logs.

I own to two 610s there great saws and they don't pick your pick your pockets like other saws 😆

Well this is the second time I’ve watched this video. Haha “recycled toilet paper”. That was good for a laugh. Just taking an interest in McCullochs lately. I ported a little plastic mac and It looks like it was in one of those broshures but under one of the many model names they used over the years. Mine is a PM425AV which is the same as the Mac 3200 3516 etc. Sticker on mine says made in Mexico but another one says made in Taiwan. They have that same boxy look to them. When I first layed my hands on one I thought what absolute junk and now it’s my main cheap bush saw. No drama from it just runs great and even better now that it’s ported. Does not leak a drop of oil and simple to work on. Smooth to run but plastic so you can’t drive over these with a tractor and get away with it lol. Another thing is it starts in 2 pulls. I will keep my eye out for a Pro mac 610 or 650. You can really here the difference in that 650. One thing about not buying anything new is that I won’t be able to say “ I got that 30 years ago”. Lol

My grandpa has a McCullouch 610 he used all the time when he used to heat his house with wood. Last time the saw was used was 1987. I wanted a bigger saw and am too cheap to buy a new one so I drug it out of the garage and dusted it off, put new gas in it, pulled it over about 8 times and it fired right up. Couldn’t believe it. Sitting 35 years and it runs like you just used it last weekend. They don’t make ‘‘em like that anymore

..Buckin' Billy Ray Smith would love to have that McCulloch shirt you are wearing!..of course, he would cut(or tear maybe?)the sleeves off of it.. :)

One thing worth mentioning mac's don't over heat like the xl12 do on a warm day the gas boils in the homelite making them hard to start I don't care how rich you run them I am not a hater I love my homelites I took down a 36 inch ash at 85 last fall it was hard as a rock never over heated one pull restarts I don't think my 10 10 pro mac would have did nearly as well love my 610s thay cut way out of there class just bomb proof thanks for everything

I love Macs too.

Hi Mr. Obsoletes Vintage Homesteading, a friend of mine needs the Blessing of your wisdom to solve his problem:) His name is TazMan and the video is -How to remove an automatic oiler on a McCulloch 1010!!! If you have time Bless him by helping him solve his oiling problem!!! May God Bless and Protect you and your wonderful family!!!

That 650 is impressive.

I picked up a promac 650 for $25 things a beast small adjustments to the carb and sharpen the chain

Great video, I learned a lot. Thank you! I acquired a Promax 650 that runs great. I have one question, what degree do you sharpen the chain at. Thank you.

Also, heavy saws do not exhibit kickback tendencies, like light saws. My saws also have big dogs and I dig them in when cutting. I don’t think they will kickback, even if I do something stupid, but as a kid I learned to keep my eyes on the bar tip at all times.

An update on your saw. During the second round of testing I ran into a leaking carb issue. The air box filled up with gas. I am currently working on replacing the faulty carb. Hopefully I will be finished with it this week. I have a spare ready to nearly ready to go. I just want to be certain you are getting a good saw that doesn't need repairs. I might get delayed again. My dad just spent two weeks in the hospital and we are scheduled to have our new baby this week. She will be induced if she doesn't go naturally on Thursday.

I have a pro mac 610. How do I adjust the auto chain oiler? I bought it new in 1982 & always had to use the hand oiler It has been a back up saw because of that so never got used much. Yesterday I took it off the shelf (stored 6 years) with fresh gas & a shot of starting fluid it fired off on about the 3rd pull. I would like to adjust the oiler & realy start useing it. Thank you

AWESOME Video sir! Do you happen to have any information on the pro mac 655 from that era? I have one and it's awesome but I can't find much info on it, I know it's 60 cc and from the 80's. Any help is appreciated! Cheers!

I have the montgomery wards branded saw from the early '80s. I always thought the bar oil only came out manually. Are you telling me I've been hitting that plunger for the last 40 years and didn't have to? They were built like a tank. Only the chain and plug have ever been replaced.

Nice! I'm gonna bust mine out!

Sad how all these companies got bought out or went out of business. I heard those Timber Bears were sold dirt cheap.McCulloch was trying to save themselves maybe or just clear out inventory like you say.

Hey Mr. Know any information on the PM605? I have one it’s black and silver, and I have my PM650 I love to use.

Just used the heck out of my mid `90s, made in mexico timber bear today. Need to look into the fuel pump, had to run with partial choke. Other than that, she was barking with a couple feet "rooster tail" of chips.

Hello agine sir I had mentioned I picked up a 610 but I couldn't find any id tag any where. IT was right on the front of the saw just below the plug serial 11-048017 and the mod 600041c .If You would sir could tell me what I have

What size bar are you running on your timber bear? I bought mine on eBay for $100 shipped back in 08 I think. Best saw I have ever owned.

Back with you here learning. I believe I paid too much. But, since I'm not very mechanically inclined to say the least (my youngest brother is though) So. while searching for a vintage mcculloch chainsaw either a 610 or 10-10. I came across a one owner, very well care for like new Mcculloch Timber Bear with s 20" bar, on the Bay. I offered the nice gentleman...first $135, then $155., But, he didnt accept those offers. So then I bid his intial asking price of $179., and I won the bid...I know a majority here and you my Chainsaw Sensei. Are/May say I paid too much. But, I couldn't help myself...I suffered from temporary insanity and had to have it...Now, I just have to try and find a manual for this saw. I think I'm getting a bad case of Mcculloch fever...

I just bought a really low hour pm 610 thats had porting done.i expect it should cut about like a 650

Should've mentioned how easy it was to get the air filter cocked letting dirt in. They were also damned loud!

Do you have some Stihl chainsaws? They were also good at the time when they were build like a tank ... Btw your videos are ASMR type of videos . Always watching before sleep

My 610 is great. I feel it has low compression for a 60cc saw. My 590 echo is higher compression to pull over than this one. You think it’s about time for a rebuild?

I'm just learning about these. My grandfather swore by them. I have his pro mac 650. I just got it running. I'm curious. I don't see a chain brake on yours. Did you remove it? I don't see Gpa putting stickers on a 610. Do I have the pro mac 650 you think?

Hello there i like your videos keep up the good work id like to ask you some questions about the Mcculloch timber bear

Any way you can scan that that 1976 ad and send? LMK

Can't agree with you more.

Great video Mr. Obs! I have seen some 610's around here. But knew nothing about them. I have a Pro Mac 510 37cc not running (yet lol) were they a "hot" version?

Is the 605 about the same minus about 2 cc's?

Could you make some videos of tearing down your saws to inspect the piston and rings for wear??? Great educational videos. Can't find McCulloch's on the East Coast!!!

You didn't specifically say it but I understood from the video that McCulloch made that saw for Montgomery Ward and it is literally a different color 610. Is that correct?

There is a big difference in power between a 6-10 and a 610 but still good saws

I just bought a ward 3.7 model , super clean and has a " DOOBIES SMOKE SHOP" sticker on it all for $40 ! When i got to the mans house to pick it up his entire family was there . I gave them the money and out of nowhere someone started stringin a fiddle so i started kicking my heels and jigging my feet and next thing you know it was a bonafide straight up hoe down !

I just bought a 1980 model 610. Is the handle supposed to be attached to that flat metal plate at the bottom? Mine isn't attached and I can't see any way for it to be. I bought the saw from someone on Facebook Marketplace. The guy brought me the saw and said he hadn't cranked it for a long time. I kid you not, I didn't even notice where the choke lever was and just turned on the ignition switch. I saw it already had gas in the tank and it started on the third pill with no choke. I turned and looked at him and said "I'll take it" .

What ratio oil should a guy run in these old saws?

..McCulloch, like you say, was having numerous problems at the end..but I think what really finished them off, is that they had no "modern" designs that would meet the new, more stringent, EPA standards..about the "3.7 Timber Bear"..I never understood why they decided to reduce the displacement on a saw that was already quite heavy even for a 60cc saw..I can't see how having the cylinder and piston made with a slightly smaller bore would have reduced their production costs..makes no sense to me...?..anyways, I love these old saws! :)

Once you go Pro Mac, you don't go back. I went down the Mcculloch rabbit hole years ago with a 550 super and never left. ; counselling, therapy?

Great channel! I’ve acquired a ProMac 655 “Professional”. Do you know where it sits spec wise to the 650? Doesn’t seem to be a whole lot of info out there. Cheers and keep up the great content 👍

Hi Ol' boy!!😀😀 I'm glad you love them old 610's. I've been a professional logger almost all my life and you couldn't make me use one of them to try to make a living with. I ran one for about a hour one time. I felt that they were the clumsyest most unbalanced chainsaw I ever ran in my life. A pro Mac 700 was one of my favorite Mac's I ever had. Also the pro Mac 1010 was a really great pulpwood saw. 3.5 pounds is a lot of weight if you are going to use it for 8 to 10 hours a day cutting wood. If you think extra weight makes it cut faster, then you need to do some work to your chain. Like sharpening it and adjusting your rakers to allow it to cut at full potential without ever pushing on it. I'm not trying to be mean. I'm just starting facts from my years of experience making a living cutting timber. I'm actually a Stihl chainsaw lover. I've never seen a Mac outlast my Stihl's unless they are both just sitting on a shelf and never used. LOL!! It's all about who is running them and taking care of them as to how long they will last. They all made good models and bad models. But Stihl was around long before Mac's and is still here long after the Mac's are gone. Take care my friend and stay safe and healthy!!😀😀 Logger Al

I just watched some DA calling himself a farmer that was trying to start a 610 that had not run in 30 years,and kept cutting it off when he got it running because the chain break was on. Worse yest he was working on it on his concrete front porch. I can only imagine how much paint was left on the sprocket cover because he had turned that side down on the rough concrete to work on it. He could have probably gotten it running if he had taken the chain break off. Millennials think they can rule the world and can’t even crank a chainsaw.

Sir that has to be the best $35 that anybody ever spent

I have one series 610 promax I'm Indonesian

For the love of God... can you sell me this cataloges and send me to Buenos Aires?? Please?? 😢😢😢

The mixture on those saws is wayyy too heavy.
