Very interesting Justin - I have never seen a 250 with a black top like that. I have seen yellow tops and a few late model saws with the short black cover but that one is different from the ones we see over here.

Hi Mark,

I have 2 x McCulloch 250 saws, and 2 Super 250 saws. I will check them tomorrow but I am sure they are also Black top saws.
 
I have a 1-86 Mac that is a beast. I have run it a few times. With the 3 to 1 reduction the chain speed is very slow. It seems to be for occasional use. It weighs 32 pounds plus the bar and chain. It sure sounds healthy when it fires up. I have a healthy respect for the guys that ran saws of this size for a living.
Got to figure in that these guys were using chopping axes and crosscut saws so a heavy Mac chainsaw did not even feel heavy to them.
I've got some of them old 1-40 to 1-50's area saws. Have one that is OEM, good runner with the original owners manual and just a few chips in the paint and possibly the OEM chain. I play with them when I get a big log down so as I can use their weight to do the cutting. (not for my exercise, it's to exercise them) I can see the guys that made a living with the Macs actually dreading having to go back and use the AXE and crosscut when their old Mac that they liked was broke or would not start.

Okie, you make a good point. People don't know, forget, or it just never dawns on them, chainsaws have only been around since about the 40's. My dad was born in 1923 and started climbing as a young teenager. They did residential removals, over mansions with slate rooves. I remember tying Dad's Disston DA211 on his rope so he could chunk down big trees in gardens where they could not drop the log. If they had big limbs to rig down, it was all done with hand saws. This is Dad's 42 in belt saw he used before he got his first small saw. I put the helper handle on it when I hung it on the wall. After this one he started using the Teflon coated curved saw, wood up to 10-12 inches was still faster to cut with the hand saw than wait for a groundie to tie a saw on, pull it up, tie it to his belt, make the cut, and lower it back down. Even when he started using small saws he kept the curved saw on his belt. He was the most powerful man I ever met. When I was 15 I bought a 1955 IH 1 ton truck with a blown motor, inline 6. He bought me a new motor for my birthday. Couple years later he was cleaning up around our junk pile, when I got home from school, he asked me to help him throw the engine on his F250 to take to the scrap yard. I took to long and when I got out there, the engine was on the truck. He put a big block of wood behind the truck, flipped the engine up on it, then flipped it up on the truck.

rarefish:

My dad had a bunch of them one man and two man crosscuts. A slight learning curve to stay in tune with a guy that knew what he's doing using the two man crosscut as a grasshopper.
Had to be careful or the grasshopper would eventually get a big shoe toe to the behind if he did not pay attention and listen to the verbal instructions. Not a time for Attention Deficient Disorder. (ADD)
kerosene (coal oil)was the lube sometimes used from a whiskey bottle carried in the hip pocket. Had to be careful and not go down hard on the bottle.
First Chainsaws were so heavy that lots of the old stout old time loggers preferred their cherished their crosscuts and lots of the old timers were not very mechanically inclined yet.
Kinda like when we first started seeing computers and cell phones.
I need to dig out some of my dads old one and two man crosscuts from the barn and clean them up as wall hangers.
 
I've seen some of the youtube cross cut racers and it looks like they both push and pull on their saws. Dad told me the trick, back in the day, was you only pulled on your end. If you push, and you pushed a little faster than the guy on the other end pulled, the saw would buckle and spring back and hit you full in the face. Plus, if you buckled the saw a few times, the kink would set in the steel and ruin the blade. I've used some of his old 3-4 foot hand saws to cut Christmas trees with the kids, still had to lay on the ground, but at least you didn't have to crawl under the tree. I didn't like cutting 3-4 inch trees. His Teflon coated curved blade, I used when I climbed, when he didn't have it, or after he retired. I also used the smaller razor sharp curved pruning saws. One of the first times I used my pruning saw, I was cutting about a 4" limb and on the third pull, it went through the limb, I was pulling so hard, it went through and stuck in my knee cap. Dang knee swelled up and got so stiff I could hardly walk, but I was afraid to tell my Dad I did something that stupid, I just worked through it.
 
A bit off topic here,but my dad was a powerful man too.He was a milk hauler for 7 yrs.& never missed a day due to being sick or vacation,or whatever.7 yrs.@ 7 days a week 365 days a yr.He used to lift 200 cans of milk chest high up into his truck,each can when full of milk was 110 lbs.He was built like an ox,never really knew his own strength.
 
North East Tennessee Saturday MAC Report

Beautiful day in North East Tennessee with temperatures in the twenties and warming to the forties. Loaded the truck to go fall some Ash, then got a text that ground was too wet. So other than loading and unloading the PM800, I saw no MAC action today.

Spend the day building a sled firewood shed to compliment my dog house of similar design. Theoretically it will hold four cubic feet short of a cord. I built it to hold three rows. Realized after the picture that I forgot to remove the temporary braces. Dog house has battens; not sure that I am going to add that to the shed.

PS I believe read somewhere that Mark H. was a high school shop teacher at one time. I thought of that today when I stuck freshly removed 3" wood screw in my mouth - not smart as that baby was hot. Just wondered whether they taught that in shop class or left it with experience to be the teacher. I already know that it is not smart to hold nails or screws in your mouth as you may be one sneeze from death, but when there aren't enough hands ... .

Before I was allowed to run a chainsaw, my dad handed me a saw very similar to the one on the left and handed my older brother one similar to the one on the right except it had a much straighter edge. We used those to limb and trim for several years before we were turned loose with a couple of Power Mac 6As.

Hey folks want to see something very cool? New never fueled SP125C. If I'm lying I'm dying. Has a little bit of shelf rash but otherwise is super nice. All the stickers are still intact. Has a new never used H&S spike too.

(Obligatory smart-ass remark) Technically, all of us are dying, we just don't know how quickly we're going about it.... Damn that's beautiful! Why's it on the bench?
 
So this morning I pulled out the 7-10 to cut a few thick branches ready for drying. Unfortunately I didn't check fuel level and ran the saw dry.

It gets worse: Then after refilling the saw wouldn't start. I think I pulled too hard at the starter rope and something happened, suddenly I heard a metal sound and now the starter rope cannot at all be pulled, its like simply locked.
I tried taking the starter recoil thing apart, but stopped myself, since I have never opened a chainsaw before, and I better get some information before I go out a one way street without being able to turn around.

So, my chainsaw has become a project saw. Any tips and pointers as to what I need to do/where I have to disassemble or open to diagnose how serious this problem is?

Thanks, from a beginner.

Just send it to me. I’ll pay shipping
 
Yokosuka - check your inbox (the letter icon in the upper right hand corner of the screen).

The BP-1 is back together and fully operation once again. I will point out that I have been contacted by a member who has offered a fuel tank and fuel cap to replace my smashed one, I guess the saw destined for the shelf will look a bit more like it should...eventually.

For those of you not familiar with McCulloch Auto-Mac chain, feast your eyes. The round stone that sharpens the chain has a steel back plate that touches the clutch drum when it is pushed forward to the touch the chain so the wheel spins while grinding the chain.

I am beginning to see some of the differences / changes that were made on the BP-1 saws during their short production run. It is pretty interesting and understandable to see some of the things they changed. Modified Mark noted the number of Service Bulletins dedicated to the BP-1 saws, clearly McCulloch was busy thinking on the fly as the saws were being produced.

View attachment 885652hi fellas, was wanting to know if I have my lines hooked up to my carburetor correctly. Does that top nipple need a hose hooked up to it? Its a mcculloch double eagle 50 with a zama m10 carb. It will start with mix put in cylinder but immediately dies after that like its not getting gas. Any help would be greatly appreciated thanks.
Does this help any?


If not, well at least I'm giving your post a little bump. ;)
