I thought my neighbor liked me but then he gave me an early XL12. Not so sure now.
It has a wick type fuel filter. I am having trouble trying to figure out how this works. I get that you want the saw to be able to draw fuel no matter what the orientation of the saw. Can some one explain how the wick accomplishes this?
There is a large washer loose in the gas tank. The parts blow up shows a stud, spring, felt washer, and other parts in the tank too. They are not in the tank so maybe they were removed through the gas fill port. The wick seems firmly attached to the cover. I have removed all the parts down to the gas/oil tanks cover and removed the cover screws. I don't want to damage anything so I have lightly tapped the cover with a hammer. Then I put a wood chisel on the cover seam and tapped on it. The cover won't break free. Don't know what someone used to seal the cover. My inclination is to just put it back together and see what happens. Did need to dissassemble to clean out 60 years of gunk.
Will the fuel system work as is or do I have to pull the cover and replace the small parts in the gas tank?

If it is all still intact I would fill the tank shake it around and drain. Do it a couple times and try it. I have several with wick filters and haven't had a problem with them.

I have a few saws that have the wick filter as well.I've found that after you've cleaned the filter like Classec said,I fill the tank a final time & let it set overnight to saturate the wick.

If the small parts are missing the wick will not function. You will be drawing fuel from the tube port only and not through the wick. There will be no fuel filter on the tube and once the fuel gets below the tube the engine will run lean or not at all for lack of fuel, assuming it is held upright and not on its side.
I think the tank will have to come apart to replace those small parts so the wick works normally and pulls fuel from the bottom of the tank to the inlet tube. You could change the tank for one you can disassemble, replace it with a newer tank with the top fuel port, or bust that one open hoping for the best. After careful drying of the tank, you might try heating it a bit to loosen whatever is sticking it together. There may be black goo along the seam from the factory or some other sealer added later by a rebuilder.
Do not apply heat to a tank with fuel fumes inside.
Good luck, the early ones like that one are very satisfying to get in good shape.

Thanks for the help. The fact that there is a big washer (too big to fit through the fill opening) loose in the tank and no loose small parts lead me to believe that they were removed at some point. The saw seems to have good compression and the piston and cylinder appear in great shape when viewed through the exhaust port so I should be able to get it running. I have ordered a spark plug boot and spring and a carb kit. I think I will put it all back together with the new parts and see what happens. I really don't want to break gas/oil tank cover trying to force it.
I would like to get the XL running so I have a second saw when I get the Super stuck. Also nice that both use the same gas mix and chains.

Do not run the saw lean, if you do you should expect piston/cylinder damage. Later XL12 tanks with the top fuel line exit will work on that saw, its an easy swap. The starter and flywheel need to come off, then three screws that hold the fuel tank.
Get a plastic wedge or two to help prevent getting any saw stuck. As soon as there is room in the kerf behind the bar, insert the wedge to keep the kerf open. It only has to be tapped in, it does not have to be driven tight.

Ditto on the plastic wedges. Last one I bought had a metal plate bonded to the head so you don't chip off the plastic.
