Great find Willard, and a classic saw for the collection. Despite their age, they really don't feel like old saws when you run them. Really ahead of their time when they came out. I've got 5 of those things, and I run them frequently. (same for the "little brother" 49SP. Together; the original 50-70cc "2 saw plan")

One of mine has that missing paint/corrosion/oxidation issue in the fuel tank. You can live with it on a saw that will only see occasional use. Fuel filter should be changed a little more often. And it's best to run/dump the fuel out after each use, which also provides a rinsing effect.

Chain brakes for 70E's were actually an option and can be found on either early or late model saws.

Willard, you have mentioned the Nordfeller attachment before, how was it connected to the saw?  I have a air line you can use with a car engine by inserting it in place of a spark plug but as a chainsaw is a single cylinder, ...?

Willard a thought on the corrosion being mainly at the top of the tank.  I was taught to either keep the fuel tank topped off or if storing it for an extended period of time, to drain & dry it.  The reason is to prevent condensation damage.  If the tank was partially filled, the fuel would have protected the lower area but allow the open air area to corrode.

I use my saws frequently enough I just keep the fuel topped off.  (Ethanol free of course!)

Congratulations on the great gift!

Spike 60  I never owned a  70E when I worked the woods back in the day. I went straight to the 910 Jonsereds when it became available a year or so after the 70 was introduced.  Then when the 910 and 920 were wore out I bought the newly introduced 630. My brother did own a 70 and he said it was a big improvement over the 621.
I may soak the fuel tank in some sort of solvent to disolve the corrosion . I used to soak my tea corroded stainless steel thermos bottle with water and denture cleaner tablets....worked really good :D

Oliver I believe the Nordfeller option was plugged into the cylinder with a connector like on a air compressor and air hose. The cylinder port would probably be like a decompression port.
Im awy from home for a few days so can't check the 70 to see if the cylinder has the port.

Winters just around the corner here and just finishing up organizing and putting things away.
Well I picked up the old garbage dump find Jonsereds 70E  and sprayed some solvent down the carburetor venturi and then cranked her over to spread it through its P/C. Well I got a shock of a surprise when it fired right up.......I guess it'll be an earlier restoration then I anticipated :D

Sounds as if you have ignition and compression. Just a weekend project!   ;)

Its got lots of compression, probably why it fired up so easily on the solvent. I was just surprised it had spark seeing the track record these old saws had and 36 years later.
Funny how something can be so worthless to someone to just throw it away when it only needs a little work.
I wonder if our sponsor CHAINSAWR has a air filter , filter top cover and a chain brake lever for it?

The widow of an older friend of mine had a 70E that her husband used before he died. Looked nice, but wouldn't start when I put in fresh gas and cranked it over a few times.

I actually bought an old Husky 51 from her for a friend -- it ran great. It was when I was buying this a few years ago that I saw the 70E. I did not have any tools with me, and am far from a chainsaw mastermind, so I have no idea what the problem was.

If you are interested, I can see if she still has it. Not sure if it's repairable or just a parts saw. Just let me know.

Thanks for the offer John. I do know of several in my region here, but appears searching on google there's still lots of these 70E parts available.
Easier for me to get parts here in Canada then all the hassle getting things shipped across the border from the U.S. with customs and all.
