McCulloch Chain Saws

The 82 cc McCulloch saws are really something special.

Joey Taylor and I decided to line ours up one day (some while ago...)

Woodruff keyway worn? Timing?

The only way the timing could be off is by the air gap on the coil to flywheel.I have it set to specs.The woodruff key was fine whjen I put the FW on.

If I'm right I counted 16 saws,that's 1312 cc.s of pure Mac.

Fall will soon be here and the snakes denned. Time to put some 82cc MACs back to work.

I got a 3-10 in the mail today that I bought from a guy on FB.It's gonna take some work to bring it back to being a runner.The recoil needs a new rope & handle,absolutely no rtope on the pulley whatsoever.The fuel tank had old fuel left in it till it evaporated into goo,along with the fuel line.I've got goof off soaking in it now.The saw did have spark & fired on a prime,but with the DSP in the off position.It's supposed to have 142 psi,but I highly doubt it.Now the only saw left in the 10 series for me to get is the all elusive 4-10.

The only 70 cc model without a DSP or compression release.

May just be mountain logging folklore, but I was taught that an idling chainsaw on the ground would keep the snakes at bay. Come to think of it I have never come across a poisonous snake while cutting around here. On the other hand, when my dad was logging in central Florida, he regularly brought home rattles from the snakes he killed. He once brought back an eastern diamondback that was over six feet long. I don’t believe we have those here in upper East Tennessee - just a few timber rattlers and lots of copperheads.

Hi Mark,

I thought a 4-10 was 70 cc as well. No decomp on mine. Kind of hard to find them I guess. Acres has them listed incorrectly but found it as 70cc in mac service literature a while back.

Ed is looking for a 4-10, the only 70 cc model without a DSP...

Ahhh, saw the 3-10 and thought that was what he was getting and you were commenting on.

Completely glossed over the 4-10 info My mistake...

Well finally the 610 build is a runner! I put the ignition module on from the Monkey Wards saw I got the other day & it fired right up,BUT....it's acting like it has an air leak.I turned the idle screw out all the way & turned the lo needle out as well.It cut down on the saw screaming,but now is blowing dark smoke due to being too rich.I only changed the PTO side crank seal,so possibly it's the FW side seal that needs to be replaced.When I put the engine halves together I used a layer of blue silicone,so it shouldn't be leaking there.I also made sure all the gaskets were in good shape on the intake.

Vinny had made a post about using Goof Off which is an acetone based grafitti remover.I bought a gal.of it & it works wonders on varnished fuel tanks.I put some in the fuel tank of the 3-10 I just got & ya gotta be careful with it as it really does nasty things to rubber/neoprene based products.It made the stuck in the tank fuel line as slippery as snot,but it did loosen it from being stuck to the tank.I ended up pulling the tank's top cover off & a good thing I did.The PO had used a silicone sealant to "seal" the tank,no gasket to be found anywhere.Maybe it worked at one point,but I wouldn't trust it.Here's a pic of the 3-10's fuel line portion that was in the tank with the goof off.

I've never seen any snakes whilst cutting either, must be true!

That and some BB's makes for a great tank cleaner. BB's are reusable. Shake and Bake !!

Decided to go ahead and tear into a little 110 I got for 5$ the other day. Now I remember why I quit working on those! Tuff little scutters to get apart if you haven't done it for a while.
