I have never owned anything other than an electric saw, but when my Grandpa heard I was dabbling in log milling, he gifted me his old Jonsered 16” chainsaw. He told me it’s going to need love and some work, but it’s a good saw. Where do I start? Resources? I am not a “small engines guy” and don’t know a lot about the inner workings of anything other than basic lawn mower or snowblower maintenance. I am really looking forward to rehabbing this thing though. I love to restore old hand tools and fix things.

Here’s what I would do:
New carb kit
New plug
New chain
Lube the bar
Fire it up and cut some wood.
Done.

Yup… you can put some fuel in and see if it will start (or at least try to) before doing anything else, but chances are that saw has sat for some time, so the carb is gummed up, fuel lines cracked, etc… You can rebuild the carb for a few bucks, replace the lines and filters, etc… but the price adds up quick doing it piece by piece like that. Fortunately, you can get a tune-up kit for around $20 or less that will include everything you need to get it running like new. They will come with at least a new carb, air, fuel and oil filter, new fuel and oil lines and a new spark plug.

I’d hold off on a new bar/chain until you get it running and see how they perform. At the very least, get a sharpening file for the chain so you can keep it sharp.

Cheers,
Brad

PS: To keep it running good after you fix it up, always drain the fuel and run it dry prior to storing.

Yeah, all sounds reasonable. I love doing things myself but I was thinking about taking it to a small engine place to be done with it. I don’t think I can though, I’m too much of a tinkerer. I like learning.

Pull start is awful, but I am thinking hydro lock or something there. I’ll have to take it all apart this weekend.

don’t forget that chainsaws take a 40:1 or 50:1 2-cycle oil/gas mix
and also a special “bar chain” oil. available at most box stores.

Some folks think STA-BIL is not much more then snake oil, but I use it and love it. I add it to the gas for my lawn mower, and all my 2-cycle mix gas tools also. When we moved here 5 years ago I had to rent storage space for almost a year and a half till I could put up a storage building for my mower and yard tools. ALL my gas powered yard tools had the Stabil in the tanks (2 chain saws, 2 weed eaters, a hedge trimmer and a leaf blower) and every one of them started up with nothing more than pour out the old fuel and put in some new fuel. You can believe this or not but I did this myself, not my sister’s brother-in-law’s father’s cousin…. ME!

along the Sta-Bil subject, ethanol will destroy old fuel lines.
try to find a source for Non-Ethanol fuel and use it religeously
in all your motorized yard equipment.
if you do take the chainsaw to the shop, insist they change out the old
fuel lines to “Ethanol Tolerant” lines. well worth the investment.

Generic 2-stroke oil like the stuff John posted really shouldn’t be used for chainsaws, as they run a lot hotter and faster than normal 2-stroke motors. For just a bit more money, get the good stuff designed for chainsaw use, like the Stihl (either one, standard orange or the newer synthetic) or Echo oil. It has reduced emissions to keep the exhaust screen from clogging up, and it also has fuel stabilizer already included – so you won’t need sta-bil or any other additives.

Cheers,
Brad

Glad it works for you… and I’m sure it does, but that is rated TCW-3 – which is a NMMA (National Marine Manufacturers Association) rating for suitable in water cooled outboard engines. I’m no expert, but I do tend to listen to those who are and have multiple lifetimes of experience in such things… here is a typical statement from one such expert arborist:

The water cooled formulas (or multipurpose formulas) have a “W” in their designation like TCW or TC-W3. Even though these may state that they will also work in chainsaws, OPE manufacturers like Stihl do not recommend you use them in your air cooled chainsaw, trimmer, etc. Chainsaws place different demands on their engines than outboard engines and snowmobiles.

Just saying :)

Cheers,
Brad

PS: Just checked the manual for my Stihl – it specifically states not to use TCW rated oil, or oil that is formulated for multi-purpose use (air and water cooled applications).

That is some very good advice here. That is all I use after I lost two weed eaters and a mower to ethanol. That stuff is poison to a small engine!. Even after carb, lines and other parts, I never could get them running right again.

In my stihl weed eaters and blower all I use is stihl oil. Why take chances. I even use it in my poulan chain saw.

And make sure your sta-bil isn’t too old, it has a 2 year shelf life.

Sometimes old saws are not worth putting dollars into.
Carb kit, new chain,new bar etc. Doesnt take long to reach the price of a new saw.
Not saying that youre saw is not worth a few buck but ive been down the road before and finally gave up and got a new saw.
And you cant beat this fuel,10 year shelf life and premixed.

Whoa, ok! Now we are getting some in depth knowledge dropped around here! I never had heard anything about not using “car gas” in the lawn mower. Haven’t ruined one in 12 years of it yet. I won’t take chances with a chainsaw though. What about this stuff?

I have bar and chain oil for my electric already.

kocgolf, are you planning to use the Jonsered in a chainsaw sawmill? How big of a saw is it? You’re going to want some power and a longer bar. : )
