McCulloch 840

I picked this saw up in January. It had been setting for maybe 20 years with a full tank of gas. The tank was in pretty bad shape, heavy varnish on the bottom and corrosion on the top. McCulloch flat back carburetor was really gummed up as well, and the metering diaphragm was stiff as a board, I still have it soaking but not much hope in my opinion.

The 840 as it arrived, behind the 1-60

I took this one all the way down, new rings and seals, bearings were good, had to sandblast the inside of the fuel tank then gave it a coat of POR15 on the inside.
This one came equipped with a 36" Oregon bar and 1/2" pitch chain in good shape. Now it is ready to run and will accompany me up to Grandpatractors for a little run time this Saturday.

I had to change the sprocket shaft but BIG THANKS to JJ I had one of those on hand, and find that the threads on the other end are to run the oiler on the side of the gear case.

O.K., I did repaint the air filter cover

I only want to see this view when it is setting on the bench

That 840 sure is looking good, Mark...

Maybe you guys could make a video when you're up that way?

That is one mean looking beast. I'm with JJ, post a video if you can. If only to hear that bear growl!
Thanks for the pics

Sad case that I am, I still like the sound of my 1-85 best of all the saws. Must be something about that muffler and just the right amount of it burned out.

I have the round muffler (without the perforate metal baffle) on the 840, not correct according to the IPL picture but the part number agrees. Makes quite a bark but not as rich as the 1-85 to my ear.
