Hello
My name is Joel Dixon i am a 20 y/o male from Newfoundland Canada, i have little to no knowledge of small engine repair but i have recently made an effort to start to learn, by throwing my self at a chain saw repair job. i have a shtill that i us for wood cutting so i didint want to tamper with that until i knew what i was at. i got 2 chain saws on my local classifieds for 30 bucks, they are both pioneer chain saws. some pictures will be attached, i really want to get at least one of these saws running while learning about the mechanics and how to do a few things like carb cleaning and all that! Im going to need some tips and was hoping someone could maybe point me in the right direction and maybe where i should start!, i havent tried them yet because i just got home late with them and dont want to wake the neighbors. the guy i bought them from said he couldn't get one to run and the other ran and shut off. really really want to get this started tomorrow cant wait to start! any help would be appreciated!!

From the most inexperienced mechanic ever

Well, get yourself an ice cube tray or egg carton to put pieces in when you disassemble anything. That will help you keep track of the order you took it apart.

The condition of the piston is a critical diagnosis aid on a chainsaw. Usually the piston can be viewed by removing the muffler. (and the carb to see the other side)

Fuel hoses and carburetor rubber parts tend to go bad and may be all that's wrong if the saw's been sitting.
 
Pics taken during the disassembly process can be helpful. Sometimes if you have to order parts, it will be an extended period of time before you put things back together.
 
They look lime fun projects. I'm not much into vintage saws but the three rules to small engines applies ( fuel, compression, spark.) You have to have all three or it's a no go. First check compression, possibly remove the muffler and inspect the piston to make sure it's not toasty. This is done with a compression tester you should be able to get at n.a.p.a.

Next check for spark, inspect your plug and check the gap.

If compression and spark are good then look for a fuel issue. That could be anything from a bad impulse line to fuel line, or diaphragm in the carb.

Start there and be sure to post any questions you have as you work your way through this lots of good people here willing to help.
 
It has been 20 or so years since I have been into one of those, but the usual advice won't apply here.
As I recall, some serious disassembly was required to get to the muffler. I remember this because the muffler screws would work loose, and the owner would keep running, and the hot exhaust would melt the air filter cover, and those were real hard to find 20 years ago, I am sure now is even worse.
Also, the easy arc system involved an auto compression release, so a compression gauge is useless.

And this is to keep in mind, all parts except the carb kit will be nla, or at least extremely difficult to find, and
extremely expensive if you do, so keep that in mind before you take it all apart.
The best thing to do to start, is to squirt a shot of gas mix in the carb, and try to start. If it starts then dies, then go through the carb/fuel system.
 
Good advice above. Please don't get the urge to spray it with carb cleaner. Like the others said, you will very likely need a carb kit, fuel line, and hoses. If you have access to an ultrasonic cleaner, they work wonders on these small carbs. If not, get yourself a can of Berryman Chem-Dip to soak the carb in. The stuff is nasty so the first option is much better. Probably a good idea to get a box of at least 5 mil nitrile gloves. You can google the name on the carburetor and find the repair manuals and parts break downs for most types. Some carbs have check valves that are obsolete, so be careful if you poke a wire through the holes and it's also a good reason to limit the time in the chem-dip. The Pioneers you have were good performing saws for their time.
 
The exhaust port is on the bottom of the saw on those. You have to take the shroud off underneath to get all the screws out. That second saw you posted is likely a P-26 electronic, and very well could have no spark. Coils are hard to find.

Air filter covers are on eBay, the filters are a little more rare.

Those are very easy saws to work on.
 
Guys here is the saw taken apart to some degree, I hauled it over and over to no avail, wasnt easy to pull wasnt hard either, i pulled out the (Choke?) and still nothing, so i started to dismantle. when i turned it on its side the black fulid ( Gas?) came out from this metal box on the side (muffler)? i took the it apart it was wet inside with the same fluid, in the picture you can see i am pointing to the spot where it was leaking from. there is a picture of the gas tank and a very white (fuel filter?) i also want to know what the part is on top of the saw directly below the cover toy can see it open and closed! (the carb?) and pull lever (Choke?) opens and closes it. Pulled the spark plug and the seller must have replaced it with a brand new champion spark plug and it worked fine lots of spark, not wet and not dirty. So i have spark! where should i go from here?? if you need more pictures/ info let me know!

thanks a million

Joel

The fluid is likely fuel that has seeped into the crankcase from a leaky carb, coming out the muffler.
Please be careful about and spark
with this much fuel seeping about. The next thing to do is remove the carb, and read the brand and model numbers off of it. You also need to educate yourself a bit about the carb.

Okay!
how should i go about taking off the carb? any idea?
 
You still need to get the muffler off and look at the cylinder and piston before you put money in it. You need to remove the bottom shroud and the phillips screw that was left in the muffler when you removed the muffler cover. I believe there will be two more screws under the shroud.

Now, get some white paper or paper towels and lay the carb on it. Take it apart carefully. Don't shove a screwdriver under the covers to remove them or you will ruin the gasket surface. There is a little lever inside that has a spring under it. The assembly is probably held down with a screw. Don't loose the spring! Pay attention to the H screw and L screw, which goes where. Never tighten these screws or you will damage the seats in the carb and then it can't be repaired.
