Hey guys,

Working on a little mac 140 for a friend, went through the carb and got it running real nice. But, as soon as some bar oil is put in she burns right through it! We're talking oil geyser off the chain. :dizzy: When I had it apart I was surprised to see what I guess is the oil pump, thought these were manual pump only. I think a diaphragm in the pump must be bad. Did a quick search but didn't find any thing to rebuild the pump. Any reason you can't just block the crank case port and just use the manual oil pump in the tank? Appreciate any help.

If they don't mind not having the auto pump, then I think it will work just fine. I just did the opposite on a Pro Mac 1000. I made a solid gasket/plate to go between the manual pump and the crankcase as it would not stop leaking air into the auto pump system (and did not work well anyway). Auto pumper works great now.
 
A heads up for any Aussies who like the big bumble bees, I see there is an SP 118 for sale on the Gold Coast. Too steep for me but it looks OK. Look here:

Sorry for posting in this thread but I thought more Mac fans might see it.

Al.

Is that near you? A 166 is at the top of my wish list and having it in Mac colors would be more than fine. Plus, then I could race Mark at the next GTG!
 
toocheap - The automatic oiler on that little saw is operated off crankcase pressure pulses. There is an adjustment screw accessible from the front of the saw; normal position is with the head of the screw flush with the front of the case but you can try adusting it from there.

Proof positive once again that you should always keep a lit road flare in the shop at all times to clear the place of fumes ...:msp_thumbsup:

Lol, that don't sound very smart... :D The fumes would probably explode the barn...

Did I ever mention that one of the rules in my shop is absolutely no open flames or small sparks are to be anywhere near the trash can? Yep, when I'm carby cleaning parts with carb clean, or brake cleaning parts with brake clean, I do it over the trash can to help reduce the fume level in the rest of the barn. However, if something were to ignite that ####, oh boy... I bet the roof would be blown clean off of the barn.

No no! Send him a note here. It's much more fun for all of us to see the response if you guess the wrong guy again :cheers:

Too late sent it a while ago... sorry guys. As much as I would enjoy laughing at my own brain farts, I'd rather not do it again... :greenchainsaw:

Also, I worked today. Packing stuff up in plastic bags, and sealing them, labelling them, and throwing them into a box, then shutting the box and taping it shut when it was full... repeat. Did that for about 8 hours today. In the shop at work, of course. (went and helped out at dad's work. They have some people on vacation now or something, so they need me to fill a spot)

Also, yesterday, I got to really run the 850... my neighbor felled a rotten maple in his yard, and his little Homelite (mind you, newer box store one, got it for dirt cheap...) and his son in law's MS 361 were sounding slow from my house... :D So I go over there with the Mac, my neighbor helps me tune it even better, and got to work bucking up those 21" or so diameter log. Not much of it is rotten, so the saw did have to work... barely... :D

Going over there tomorrow to help with the other tree. Probably gonna do all of it since it needs at least a 28" bar for the majority of the log... This 850 will be broken in on this tree tomorrow.

Also met the guy my dad told of having a barn full of old saws... his name is Lenny. When I first heard that name, I'm thinking this guy must be quite skinny, a bit shorter than me, and possibly missing a few teeth. Talk about hitting the nail on the head... he looked exactly like I thought he would. Kinda lanky, but still strong (heck, he felled trees for years, and still does, and moves lots of logs and firewood) and missing some teeth. Definite working guy. So, while I'm cutting tomorrow, I'll make some videos, and take pics. And bring the camera with me to work Thursday to show Lenny... that may be just the ticket to get into that barn of his...

Also, my Mac was making chips on average of about 1/2" to 3/4" long and 1/4" to 3/8" wide... talk about throwing chips... it made the little saws look a little puny...

However, the guys that run those saws deserve the option of using lighter saws... his son in law has had to use many heavy saws cutting trees and telephone poles down for the county, and my neighbor used to fell huge trees in the UP with gear drive Homelites... he'd lug them things, with gas, oil, lunch, and all, miles into the woods. He wouldn't do it again, even if he were to be paid well. He said it was real dangerous. (no kidding... logging is still up there with fishing for crab in the Bering Sea on the list of most dangerous jobs in the world)

He says he saw many guys he knows or knew get killed and beat to hell from trees swinging around and such. He claims to have never caused a barber chair, since he cleaned his face cuts out well. He did have trees spin around on the stump, twist and fall backwards, etc. but no barber chairs. To be honest, I believe him.

From what it looked like, neither of them really wanted to even run the Mac, given it is much heavier than their little plastic saws. I don't blame them.

They did, however, love hearing the 850 run though, and seeing the big chips being thrown out from the clutch cover. Also liked teaching me little tips on cutting so I don't get my slightly overweight ass in trouble with bar pinching and such. Hey, I only got the bar pinched once! Not bad for a newbie to bucking up a 40' log on a quite uneven side hill, eh? I was cutting them down to about 18" lengths, if you want to do some math and figure out how many cuts in the log I was making.

Guys, I thank you again for putting up with me... I don't know where I'd be without some smacking of and rearranging of my feeble brain cells. I still learn some from you, some from my neighbor, some from many other people in my life, and I will still learn for the rest of my life. :cheers:

Oh, I also got the 1-76 entirely disassembled, minus tearing the engine down. However, there looks to be a little bit of white death inside the bar oil tank and on the stuffer plate... will post pics in the morning and we'll see if I am simply freaking out about powdered oil remains or something.

Sold!

Thanks for posting the ad Al - another SP118 coming my way!!!!!

Regards,

Chris.
 
Sorry Wendel,
It is more than 1000 miles from me.

Well done Chris. I have a couple of smaller bumble bees and would love a 118 but like I said it is a long way from me and isn't it a bit expensive? I am hoping to get one locally for a bit less!
Now Chris, when you see any big Poulans or Partners up your way, you will know who to contact!

Hey guys - I thinx there's also a 790 for sale on eBay down there .... pretty cheap from the last I saw too

Thanks Al.
I hope that you do eventually get hold of a big 118 for your collection. I am very pleased to pick this saw up for the price I paid - had a good chat to the owner about its history etc, and seems like it did not see alot of action over the years, as it was used for very large trees only. The 118 saws are pretty hard to find - especially running units in decent condition. I am waiting on some parts for my other 118 to give it a new lease on life as well.

Wonderfully built German machines these big Dolmar saws are - nothing more to be said!

Edit - I will keep an eye out Al, and if anything crops up I will let you know!


Regards,

Chris.

That is wrong on every level. Do you know I just sent a PM to every Aussie I know to get that saw? And you already have one?!?

I'm really depressed.

Wendell, just because you missed this one doesn't mean you won't trip over a 797 someday... #### happens, but it is for a reason. That's what I know from experience.

I know how you feel, I've missed out on lots of great deals, etc. when I failed to act, or someone else snatched it from me before I saw it. Like the old Homelite saw my great uncle had. That still bothers me to this day. However, I now have two monster Macs, one is running, and one is going to run fairly soon. There's an upside to it somewhere. Some awesome saw will come along just for you.

Yeah, been looking at that... problem is shipping is around 100 bucks more or less... I can't do that since it would mean giving up my cylinder boring money, and putting the .030" over 790 to a standstill for an excessive amount of time. I want to get it done, and done right, fresh paint, fresh engine, and all. I am not going to let that great Aussie 790 get in my way, not right now at least.

Thanks for rubbing it in. :angry2:

Don't choke now, but the seller quoted me about $330 AU for shipping alone.

Sorry about this one Wendell - I would think that a 166 would be easier to find over your way as I am sure that a whole lot more of these machines were sold in the US than out here in Australia? I know of a few 166 saws out here but not many in the big scheme of things. There are plenty of Mac 125's, 090's etc but few and far between with the Dolmars - from my experience anyway.

Best of luck with finding a 166 - I am sure you will - just ask Lee

Regards,

Chris.
 
Everybody over here knows that Lee grabs every 166 and all the Stihl 090s that come up for sale ... :msp_rolleyes:

Yes, Lee's collection of the big 166 Dolmars is something to behold.
Apart from the $$, I can attest to the amount of time and effort that would have gone into getting a collection of saws like that - and this is something that some guys do not understand. Only every once in a long while does a gift fall in ones lap, but often it takes countless hours of research, phonecalls, and patience to find a particular piece you have been searching for. Many, many leads are exhausted, but eventually it does come together one way or another.

Seeing Randy change his allegiance to Stihl would be an interesting day though!

Regards,

Chris.

Not true at all. One of the last 166's i bought was on the
i seen it on cl-ebay thread. It was posted and sat there for
four days or so and no one bought it. So i made the call and
bought one of the cleanest 166's i have. The last two 166's
on ebay went elsewhere. I never bid so some of you guys
that keep crying about owning one would have a chance at
one but no one here bought them. I wonder why.
As for 090's, I could care less about those unless it's a
geardrive. And i only have 2 090's and 2 090G's.

Here is the tree I will be bucking up, when the pouring rain clears up. (looks pretty clear now... been so for a couple of minutes... might head out in a few...) Did go out, and the neighbor's son in law left a few minutes ago, which means they have no plans of cutting today. It is real wet out there, so it's quite feasible to think that wet grass + running chainsaw can = death and destruction.

I did not drop it. It had many huge branches hanging over the house, and it was rotten from about 30 feet up all the way to the stump. Huge cracks all the way up too. A pro with a High Ranger and an MS200T, accompanied by a 395XP with what appeared to be a 32-36" bar (had to make sure to get through without having to walk around the tree...)

The older more experienced tree guy was nervous about this tree, as my neighbor was too... it has (had, I guess...) a twist about 2/3 the way up, (total height about 85 feet... bucket truck was a 55' reach. There still was about 25 foot of tree above the guy in the bucket... Also, it was fairly rotten, and the two combined can be very unpredictable...

You can see the rope used to help pull the tree against its lean, which was towards the house... an F-250 was tugging on that rope.

It only took them an hour and a half to limb and drop it.
