The unofficial Mac 10-10 thread

Do you change out the tank so you can get to the screws? I've got a spare h/l adjustable sdc carb, but don't see how'd you get to the screws unless I change tank or drill holes in side of airbox?

I changed the tank.. I never really had good luck sealing them but this appairently is the exception to the rule

 

[mogulmasher]

Just a little more fine tuning of low screw and this pm55 is really cutting. I'm very impressed!

 

[mogulmasher]

Unfortunately for some reason my pm700 has decided to start dying in the cut after running so we'll the last time I used it. The 55 is really showing it up today....
Not good when I have some 30"+ elm to go buck up and haul home tomorrow.

I have several of the full wrap bars still, but you would have to modify the clutch cover or find one of the old style (7-10) clutch covers to allow it to fit.

Modified later cover.

$50 + shipping to cover my cost.

Mark,
Do you still have any of these full wrap handles?
Are these aluminum or steel.
Let me know, I am interested in two of them.

 

[heimannm]

They are steel rather than aluminum, much easier to manufacture this way. PM sent.

Don't change the carburetor, McCulloch did a good job of selecting the correct jet for those saws unless you are located in some extreme altitude.

Same for the SP125 saws, they will never be lean due to carburetor adjustment.

Mark

Well I'll say this is a correct statement. Ran the 55 today alongside my 6401....well actually 55 to the rescue after I pinched the Makita. After I freed it I kept switching back and forth. Of course the 6401 is generally faster and better saw, but the 55 wasn't as far behind as I thought it would be, especially being 7cc down in size. The one impressive thing I noticed though is the Makita could/can be stopped when leaned on a little, not the Mac it keeps chugging right through. I'm very impressed.

I need a favor.
I’m rebuilding a friends mac 10-10 and it is missing the plastic stop switch base ( part number 214961)
I have a 3D printer and am willing to draw the part and upload it to thingiverse if someone could measure one up and post a dimensioned sketch of it.
Any help would be appreciated.

A few people have asked throughout this thread but it has never been answered to my knowledge. Differences between 10-10, pro 10-10, and pro Mac 10-10?

Chain brake on pro and pm and a long clutch cover on pm. Different air filter/cover on regular old black top 10-10. How about the motors, any porting difference or anything else? Seems like a couple vids on YouTube really show the pm to be a strong runner. Seems/looks stronger than regular 10-10 and pro.

 

[mogulmasher]

Chunked up some backyard firepit wood today with the 10-10 auto. I can't say enough good things about this saw, it just "feels right" in your hands, so nimble and responsive. Just the ultimate in simplicity, styling, and power......and that sound!

Don't get overloaded, a 10-10 is a 10-10, there are few noticeable differences.

So I guess one that appears to run strong is probably just in a good state of tune then. To be honest, my pm55 runs strong but oh man my 10-10a doesn't feel to be too far off from it.

 

[heimannm]

The "standard" 10-10 saws are 54 cc, the PM55 and 10-10S are 57 cc, there is not that much difference.

Yeah I know this, the 57cc variants seem to run real strong. Was just stating exactly as you say they run pretty close.

 

[heimannm]

I have a PM55 with a NOS piston and cylinder, it is a very impressive running saw indeed.

Mark

 

[mogulmasher]

Yes indeed, my pm55 is a joy to run. However, I feel the 1010a is even more fun, just seems more raw and slightly lighter as well. Tough to explain maybe......lol

 

[iwannachopwood]

^^ Oou those shavings are deadly mogulmasher!!!!! hand file 3/8? wow!!! iwannachopwood. Shout out to Mark for all kinds of parts i needed and helped me out with some info ,and fossil you guys rock!

 

[Big Red Oaks 4 me]

I don't currently own and old Macs, but back when I did, my left arm biceps got huge! Since getting rid of the Macs, I have lost a lot of strength. Pulling on those old macs was excellent exercise!

 

[heimannm]

If you have to pull that much, you are doing something wrong. I have only one McCulloch currently that is somewhat challenging to start (77); I think the biggest problem is I haven't figured out the exact sequence of prime and pull...

Once it is running though, throttle up and hang on!
