I beg to differ on the no key way on the crank statement.I bought my 1st 7-10 about 5 yrs.ago & when I went to do a test cut the chain stopped.I took the clutch off to find it was missing the woodruff key

I have a Macculloch CS50S and it's a piece of cake. Mac was great until he got to Husqarna Group, but now...
Never know with Mac it seems
Thanks Rocker,
I have another mutt I’m playing with, broken off tag
No DSP or button. Black one piece top tank with idle provision only, takes the flat air filter.
Handle is quite tall.
RH start
Reed flat muffler
Cleaned points and it sparks
Piston and cyl borderline ok looking. Many treatments of marvel and premix gas to flush some brown stuff from crankcase. Rings free, move a bit in piston groove
Gave it a fuel line and it started 2nd pull, ran, revved, quit. Airbox swamped with fuel.
I’m gonna pull and seal the tank and rebuild carb and maybe have another runner, probably 54cc, lol.
These ol macs are pretty tough.

My mutt has a keyed clutch
Talking to my wife driving yesterday and she was confused about how these mac models are difficult to identify unless you really know your stuff (like many here). I told her these 10 series are the AR15 of chainsaws. Have a bunch of parts, can probably build a saw. She understood. Wish mine was a LR308 version (6-10). Ha.
That pretty much sums it up. Good way of explaining it actually.
Vinny here has built a few odd balls out of bits. Used a 7-10 cylinder to make an AV saw. Then again that might re start the 70cc debate
Time for some new gaskets in the 2-10
I don't have a lare selection of 354 chain , so that's getting changed also.
The clutch was missing a paw spring.
Just so happened that some idiot broke one awhile ago using an impact on one ,with spare springs.
Fyi you can sneak a paw spring in there without disassembling the clutch.
Got to put some run time on it now.
The points got chipped as they or the condenser gave up.
The tank top also got changed ,as the nitrite gasket would squeeze out between the spaces when gas mix was introduced.
I also swapped the needles out on an SDC 44A to retain the adjustable needles. It originally was a SDC 2.
Does the super 2-10 take a regular 6119/20 seal on the clutch side?
Its got a little wandering in the tio tune.

Yes Ira,it'll use the 6119/6120 seal.
