McCulloch Chain Saws

[Teddy.Scout]

Your 660 looks sexy!
What parts does the one one the bottom need?

 

[struggle]

if you hang them by the rear handle, the oil stays put. Learned that by owning stihls.

Is it possible that the oil pump leaked through from sitting such a long time then or has it most likley failed completely?

In other words after setting for years with oil in it this would be normal or expected to happen

Let's just say it's not a rare occurrence.. Uh, rather than hanging up your saw, why not just drain the bar oil out of it if you're not gonna use it for a while..

I had a good day today. It started out with a full day of cutting and hauling firewood with a group of high school student from Boca Raton, Florida. Last week we had snow on the mountains today it was in the 80s so they must have brought some of the Sunshine State with them. I don’t have any pictures of the MACs in action but I used two of the PM800s today – always a lot of fun. The kids loaded 5 loads to best last year’s group by one load. They could have done six but the haul time was too long to get that done. Only had one casualty, one of the girls tried to catch a log and ended up smashing her thumb joint between it another. Fortunately it wasn’t broken but she was in a lot of pain and spent a little while at the ER.

As the last load was being unloaded, I got a call from a friend who asked if I could come coach him through cutting a tree down next to his house. As we had a massive thunderstorm approaching, I ask when he wants to do it. He replies, “Right now!” I ask him why. He says, “I been burning brush and the top of the tree is on fire.” I grab a friend who has been driving the trucks all day and we make the 15 minute trip to the house. When we get there I find he and his brother with their families gather to watch. There are two walnut trees with dead tops both with leans the wrong way and now the wind is blowing hard towards the house. I am not that good of a feller and have gotten a little rusty during my laid up period (I fell three small 12 to 18” hickory trees earlier in the day and would be run off this site if I posted the pictures). But my friend was disparate so I agreed to cut them down. Sometimes you’re right but you hate it – I look things over and tell the guy the only way I can cut the trees away from the house is going to be across his barbed wire fence. He says cut them. I then tell him that the first one is going to hit his post. He says cut it. I cut as quickly as I can due to the approaching storm. I tried to miss the post but it took a glancing blow. Next tree is bigger, trunk is larger than my 24” bar and it has two heavy limbs in the wrong places. By now you can see the lightning in the distance. I let him climb the ladder to attach a bull rope as high as he can reach. We tie off to the truck and put a little tension on it to check for soundness. GOD smiled on me as I actually put a nice face cut on it. We increased the tension a little on the rope before starting the back cut. Put two wedges in place, cut to the hinge and put a little more tension on it and she fell squarely on the same fence post. We almost got it cut off the fence when the lightning persuaded us to quit.

Loaded the gear and within one minute it was raining so hard you could hardly see to drive. I got within a mile of home to find a large tree blocking one lane of the state highway. Before I can get to the house to get a rain coat it is hailing with hail the size of quarters. I wait this out and go back. By now the fire department and a private citizen are hard at work cutting and clearing the highway and a side street. I take the old MAC out and go to work. First order of business is cutting the FD’s pinched Stihl loose. Before we’re done I pinch my saw in one of those tricky root ball goes up stem goes down situations. I get my other MAC and proceed to pinch it too. Then it starts to hail again. I can’t let my beloved saws get beat to death so I hover over them until I’m hit in the neck by a golf size chunk of ice. Before I can get to the truck it is just raining down ping pong ball to golf ball size hail. The FD loads up and leaves. I eventually get my saws out using my bull rope to jerk on the stem. They fell out one at a time and the stem didn’t hit either as it fell. All ended well. I was soaking wet from not only the rainfall but wading through a foot of water that had flooded the street.

Here are some pictures of the firewood gathering. No pictures of the storm venture.

Man if that was a GOOD day I'd hate to hear the details of a bad day! I guess nobody got hurt too bad and no equipment breakeage, so that's all good.

I see Randy likes BIG dogs.

I got the 850 out and found some chunks of poplar left over at the guy down the road's house... went down there and realized I forgot the camera... :bang: Too lazy to drive back home and get it.

I cut into a piece that left just a hair over 1" of the bar out of the end and it cut great... until the chain stretched. Tightened that and made more cuts, all went well until it seemed that the saw was going lean, then rich, then lean, then rich while idling... tweaked the carb a little and that fixed it... temporarily. Made some more cuts and it did okay, then it ran leaner and leaned itself a little more, so I stopped running the saw. Also, the clutch seems to slip at times... Compression is perfect.

What do I look at first? Carb or intake boot or something else? I heard the intake boot can be a problem.

...To answer any future questions on whether or not I rebuilt the carb, no, I did not. :embarrassed:

It was a GOOD day for me. I don't make my living outdoors but I enjoy getting out as much as possible. Being able to do some physical labor after these past few months of inactivity is great. Using a chainsaw to help a few folks along the way is just icing on the cake. Ron

I checked on the young lady today and other than a little pain she said she was doing well. She was sporting one of those aluminum braces with her hand wrapped in an ace bandage.

Nice quiver Randy!!!

Rebuild that dang carb before you dig into the intake boot. If it still does it once the carb's rebuilt, then I'd look at the intake boot. Could be crank seals too.

Okay, I'll rebuild the stupid carb and hopefully it'll fix it. Would the local creamsickle dealer sell a Zama C2 carby kit?

They're the closest to me, and I would like to get this thing in tip top shape in case this coming storm does bring some trees down.

They might. Many creamsickles used Zamas. Dunno if they used C2's though.

I hear ya on the exercise part, I sit at a desk for 40 or more hours a week, and I HAVE to get out side come saturday. I was refering to getting a couple of saws stuck, that stinks. But you prevailed, against the laws of physics and nature, and helped out your neighbors also.

 

[promac850]

I remembered it's Sunday... ain't no dealers or nuttin' op'n taday.

I tore down and cleaned out the spare C2 carby that I have, and have the diaphram soaking in oil. :hmm3grin2orange: Maybe that will work... I'm going for broke here. :yoyo:

Am I stupids?

Hi guys,
I haven't had much to post lately as work has been keeping me pretty busy but i finally got sometime today so I got the 250 out today and found a piece of dried up elm from last year about 16-18" in diameter for some reason it had a hard time cutting it. The chain kept stopping in the cut. i would get a little ways through it and then it would bog down and the chain would stop cutting, the chain is in decent shape and the saw was running pretty decent as well so i got my husky 61 rancher out to see if the wood was just that hard but it had no problem at all going right through it.
Both saws are wearing 20" bars. any idea's why are welcome.

If the compression is good, next would be an air leak, or a tuning thing...

compression was around 150 when i bought it a month or so back what kind of air leak like around the carb mount or something?
i think i got the tunning pretty decent but im going to take it down the local saw shop my buddy runs and have him final tune it as soon as he's avalable.

Is the bar and chain getting enought oil?

I really like this deadmans set up. I see this in my future once I get the garage ceiling finished in the garage. Out where I cut wood they have an old barn that is going to be taken down and the wood would be perfect for builing something like you have.

A Mac Rack:hmm3grin2orange:

 

[heimannm]

137 - It sounds like maybe the fuel pump or metering diaphragms are stiff and it can't deliver they fuel needed under load. You can try setting the H jet richer to see if that helps.

I have several of the older saws that will run fine on the bench, but put them in the wood and the old carburetors just can't move enough fuel to keep them going strong.

[cpr]

Compression is great. I'd rebuild the carb and see. Mark is right on the stiffness. Might be too stiff to really pump the fuel or open the metering needle enough. Depending on your carb, kits are either easy to get or single source.
