I found a small rubber vent part (among other things) in the gas tank of my Poulan 1950 Chainsaw. I have purchased a new gas intake filter and new fuel lines and would like to assemble, but don't know where the vent part goes.

You did the right thing . The troble with things like generators you forget about them till you need them gas goes bad things clog up in the fuel systems like filter . Its like putting your finger over the top of a straw in a glass of water if air can't get in then fuel can't get out of the tank to the engine. As long as its running now and you have power even if you have to loosen the gas cap just be careful with it and make sure you are venting the exhust away from the building good luck im on the east coast to
The needle valve may be stuck which would not let gas into the carb. I don;t think rebuild kits are too expensive. Pull the carb and take it to a lawnmower repair shop and they should have the parts. Before that though pull the bowl and make sure it has gas in it. If no then remove the fuel line and make sure gas flows from it. If no then could be the fuel shutoff valve is not operating properly or junk in the gas tank is obstructing the line.
being a 2 stoke there isn't much to tune up. the MOST IMPORTANT THING TO REMEMBER IN A 2 STROKE IS GAS AND OIL MIXTURE,too much oil will foul plug no big deal. replace plug. too little oil in gas will wash the crome lining in the cylinder off and you won't have the compression need to burn the gas any more. once you get that straight crank the saw and run it wide open, it should be quick to react to the trigger, that is no stumbling until it finally turns up. if it don't have a small screw driver handy and turn down the screw for the run mixture until it runs as fast as it can. also let idle. it should run on idle as long as you don't turn switch off. if it loads up and quits turn in idle screw until it does idle right . that's about it. also always make sure chain on bar isn't sagging too much when not running. a loose chanin will cause uneven wear on bar and make a crooked cut.keep chain sharp. they dull quick.NEVER leave gas in tank for long periods of time. after each use drain tank and start until motor runs itself dry.
check the spark plug after a failed attempt to start. If dry, then no fuel is entering engine. Did you leave old fuel in carb? if so, your carb probably is dirty: old gasoline deposits varnish, gum, and you will need to dissassemble carb and clean it.
If your's is not a brushless type then see owners manual regarding how to re-excite the generator using a battery 6 volt (dry cell) or 12 volt auto. Be careful when removing the plastic brush cover plate don't pull at just the bottom tab, pull it at the bottom tab and at the sides. Parts may become available as plant has been re-opened by Pramac.
