McCulloch Chain Saws

[homelitejim]

That's a saw you can use to chase little kids off of your lawn...

Sorry about the lack of progress on the 790... been ####ing around with the miserable POS German car in my driveway... mechanical fuel injection is fun to set up from scratch.

I promise I will boil the cylinder tomorrow morning, and let it cool off while I work some more on the car, and I will measure the cylinder and ensure the cylinder is measured twice and maybe a third time... I suspect it should be all good, but we'll find out tomorrow.

P.S. If I don't do anything on the saw tomorrow, ya'll (CPR, Wendell, RandyMac, Eccentric) have a right to smack me silly. Hopefully I don't forget to work on the saw tomorrow. :msp_scared:

Don't be so hard on yourself. Sometimes you have to get the "to do" list done before you can play with your saws. I have a big husky sitting on the bench saying "can Jim come out and play" but no I am to busy doing chores. BTW I found a beautiful Mac 1-43 at a pawn shop for $60 that is calling my name.

Look and see if there is a part number on the bar. In the absence of a part number, I am going to guess that this is a 28" hard nose .050 gauge bar that takes 93 drive links of 3/8" chain. You can back into a .404 with a little arithmetic. I believe that a 3/8 is not actually .375 but a smaller fraction. There is a thread somewhere that gives the actual lenght of a 3/8 pitch. Ron

so if doing my math right 3/8 chain is about 2.5 hundreths smaller than .404 chain how big of a deal is this when when running 3/8 chain through a standard 7 pin rim on a mac 250?

I like the sound of that 1-43... Go get her and drag her home.

does anyone know the part number or know where i could get a 7 pin sproket to fit 3/8 chain for my mac 250? i am going to try and got the .404 way but might have to switch to a 3/8 for easy buying chain.

If you're talking rim sprocket, check the local creamsickle and/or orange dealers. The size should be large spline.

If you're talking about the drum with the sprocket welded on, I can't offer any help there. Don't know what the part # or whatnot would be.

You need a 3/8 sprocket to run 3/8. A .404 to run .404. As promac610 said, if you have a removable splined sprocket, you can just buy a new 3/8 sprocket and slide it on the drum. If it is a one piece you'll need a different drum. Ron

The PM850 went home with the Boss today, he was pleased that it looked like a working chainsaw. I did a through cleaning, where it counted and left the patina intact. It can be handled without fear of getting dirty and it won't be leaving any puddles. I let him know not to use until the AV rubber and clutch drum bearing was replaced. He will bring it back to me sometime, I'll have whats needed. I had already impressed upon him that his parents meant a great deal to me and did me the favor of not offering to pay for it.
I only regret not being able to save the lable with his Dad's name on it.

Within hours of mentioning that I was going to give the 850 to my Boss, some very kind soul offered enough parts to build another 82cc. I have them, most are very close to NOS. As luck would have it, a 82cc motor presented itself, while dirty, it is also very nice, still has the original machine marks on the piston. So, in a matter of time, I will put it together as I see fit and it won't look like an off the shelf item.

I ran my saw all morning one day before I remembered that I had a .404/7 on the saw and a 3/8 chain. It did not even make any extra noise, none that I herd:msp_rolleyes:

Next time try that 404 on a 3/8" sprocket, that racket will snap you awake.

Nice one Randy!

Referring back to post 8263 and the discussion leading up to it, the numbers are now in.

Saw is in fact a 1-76. Not a problem for me as the 1-76 I have is not a runner and now I can make one really nice 1-76 and have some very nice parts left over for other projects as well.

Is the "1-75" on the left side (of the bottom) while the rest is on the right? My guess is you have a McCulloch 1-75.

Here's Mike Acres' listing for that saw:

Mark,

Happy to see you have a 1-76 in. Seems as if you and I matching one another.

Good stuff my friend

Thanks Chris - Now I just have to wait until June to go to Oregon to collect it, or find out I can't go and have it shipped. I did put a package in the mail for you this morning before I left for the airport.

I also had a few minutes to play with the other SP105 that came in the big box of saws from Washington last year. I was comparing the starter since my pal Gene in Wisconsin (mowisme) recently received an SP125 with no starter and couldn't figure out why the starter from a 1-46 did not fit. I put together a starter from parts I had around and it fit perfectly so I don't know what to do to help him, but the 105 sure looked good and started easily so I put a 36" hardnose bar on it that I had on the wall.

Too many saws, not enough time or wood...

We are headed south to pick-up a saw, not a McCulloch, the Mac deal went as expected, no deal. At least the Homelite is of the big inch variety.

 

[Duke Thieroff]

Picked up something else new today...

I believe it's a 10-10S it has a decompression valve, but the ID tag is there, but looks like it was worn off. The air filter cover was replaced with a different one. Saw is in good condition and complete, will be in great shape after a cleaning. It should be a runner, it has spark and compression.

Man, that little 10-10 is nice. Gonna have to get one of those someday.

Sorry guys, no progress on the saw, not today at least. Too busy mowing the lawn with the 317 and killing tall grass and weeds with the SS30.
