McCulloch Chain Saws

[MEATSAW]

Regarding the compression release I just got a PM700 that is very difficult to start with the compression release engaged until it gets warmed up. My 7-10 is easy to start with the decomp engaged and makes it much easier. Seems every saw has it's quirks, or who knows.

there was a question a couple pages back about he comparison between a ported 610 and a stock 610. here is a video.

i have the ported saw running a little rich so it doesn't hit 13k RPMs and blow up so it really doesn't cut that much faster. the really big difference is in the torque that it makes. i can really lean on the ported saw and it will pull through.

first saw in video: stock 610 with 16" bar, 7 tooth rim, new oregon 72LGX
second saw: stock 650 with a 20" bar, 7 tooth rim, new oregon 72LGX
third saw: ported 610 with a 20" bar, 7 tooth rim, new oregon 72LGX

13,000 is the limit? Drat.


Still gonna port mine, lol.

Then again... I think I figured out an even better idea...

Sorry, too soon to say what... It'll be a surprise. And no, I'm not talking about the 790. That will be done regardless... my idea involves the 610... and a secret ingredient...

I'm going out to tinker... try to get the 850 fixed and outta my way for an idea...

I have a SP81 like that and found that the compression release hole was carboned shut.

i don't know what the limit is, i'm sure that 13k would destroy the motor after a certain amount of time though. i've got mine set to 11,800 RPM no load. when i was tuning the saw with a tach, i watched it hit 13.5k for a second and got scared!

can you tell by the video if its any better? its hard for me to look at the video and tell a huge difference. its got to be in your hands to tell the big difference.

i've still got a pile of junk 610's, maybe i should port another and see what kind of rpm it can take. i may tune for the best cutting, which could be 12.5k-13.5??? then i could run a couple tanks through it and see if it holds together.

i must be blind cause i see "les nessman" type walls behind you. otherwise, what good is the door.:msp_smile:
btw, nice saws and shop.

I agree, nice saws. By the way, there's a reason why some of us don't post pics of our garages and workplaces! I haven't posted pics of any new saws because things are pretty dormant around here right now. Hopefully I'll have lots of pics in a couple of months or maybe sooner.

Hmmm...

So the question is about the saws. Most of the pictures of the saws are (unfortunately) from our archives. If you look into the other threads you will find many more. Two years ago I had a pretty good sized collection, then the economy...well you get the picture. If it wasn't for Tina there would be no record of them at all. I've been working in garages professionally since I was 13 yrs old, that was 40 yrs ago, consequently there have been alot of saws and motorcycles.
I thoroughly enjoy ALL things 2-stoke powered, the saws and the motorcycles are like family to me, they represent where I grew up and continue to exist. The McCullochs are my absolute favorite saws. The saws they built were designed to last, ingenious for the day, well engineered, and from a time when pride was part of the product.
When we started posting here on AS we got some grief, as we are a known dealer. So now we choose to take the quiet path as we know that everybody likes pictures and if you don't say much we are allowed to participate as we are now a sponsor here.
Please know that all questions are VERY welcome, as I truly enjoy any opportunity to discuss the saws you find photographed. Tina has been posting pictures at my request for the purpose of encouraging discussion and whatever historical knowledge we may be aware of. Some of the saws have seen wood while in our possession, while others were just welcome to have a home with us on our shelves.

So, without boring you guys with BS...Please ask questions, because I hate to open discussion when it is only for self edification.

We try to post pictures of the saws that we know will not be seen as part of someone else's collections. There are many saws that we will not post because they have been dispersed into well known collections, and we do this out of respect to those collectors.

Footnote: Mark, we knew you were interested in a certain saw we had for sale recently...but you were outbid. Because we knew where another one was located, we told you about it so you could find one of the saws you were looking for, not for our benefit, but just because it furthers this affliction we share.

The original question... Saw pictures? EVERYBODY likes pictures, me too. Just ask, there is always a story...

Okay, what are your favorite memories regarding your old Macs that you used to have? (it hurts to say that, you should have some Macs to kill trees with...)

The first saw I remember as a kid was a Mac. I think it was a 250(ish) saw. The old man used to make me do things that he thought would scare me away...I learned how to use it even though it weighed almost as much as I did 'cause I wanted to hang out with him. The most favorite memory of McCulloch's I have is twin engined go-karts on a high banked oval track in Joplin Missouri, THAT was fun! For me the best drug has always been adrenaline...

you should have been a timber faller.

These days I will leave the shop behind for the "specialty" drops, whether the money is good enough or not...they do indeed achieve a thrill all their own. It's always "do or die" when you have to land between a couple of buildings, or powerlines, etc. and not something else. Always manages to bring a large smile when they hit the ground. When you know how to make one "twist" just right to miss the other stuff...well, either you know, or you don't.:msp_wink:

 

[promac850]

Thanks for the short stories Brian...

Dual engine karts?

Sometimes I wish I was around in those days...

 

[paccity]

i posted this saw earlier in the super250 poll. picked this up today, was going to wait till this weekend to clean and evaluate , well you know how that goes . so now i have the leaded and unleaded 250's . wish the super was as nice as the 250. but good all the same. did get the super to run with a prime and left it at that for now. here's some of both.

I posted yesterday in the chainsaw section, but I got limited responses. Anyway, anybody have any experience with these? I just had one given to me as a fixer-upper and would appreciate any info. Thanks-Morgan

i had one of those one time. i think its a italian made saw. i got so frustrated with trying to fix it and not being able to find parts for it. i threw it in the trash. i would recommend finding another saw to use as a fixer upper. that PM380 would still be a turd if it was running again. no offense, just my opinion.

on the other hand, you may could buy a complete saw on ebay and use it for parts if you're up for the challenge of polishing that turd.

I've been known to be hard headed. Thanks for the input.
