Given the age of the saw and the fact ethanol was not an additive at the time of its creation I suspect you have cracks or holes in fuel lines. It is a good idea to replace the plug and the fuel filter. For the record the most common hard starting problem on a 2-cycle engine regardless of vintage is a flooded engine. We will go in a logical progression to isolate your problem. You need spark, air fuel mixed in correct proportion, and compression for the saw to run. We will test spark first like this: Ignition Coil Test by SmallEng.com (Inspect the plug once removed if wet the saw is flooded. Post back with that too.) http://www.youtube.com/watch?v=L7WNBDRG4C4 You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You do not have to bend up the electrode. If no spark post back (below and I will help find parts). I am going to continue as the saw has spark.
Remove the air cleaner (clean it), open the choke, put a teaspoon of fuel/oil mix in carburetor throat. reinstall air cleaner, and try to start it. If it sputters and dies there is a fuel delivery problem (fuel lines or dirty carburetor). This is may be helpful: http://www.fixya.com/support/r3706813-2_cycle_fuel_system_repair If still no start reply below and we will continue.

Most common problem with chainsaws and other small gas equipment not starting is a plugged fuel line. Locate the fuel line where it attaches to the Carb. remove it with a twisting motion and see if you gas mix flows freely.
If it does not then dump the gas in the tank- leave the cap off and blow air, by mouth will work just fine but if you use compressed air be very careful to use very low pressure -- once the fuel line is clear rinse out the gas tank -- check the fuel line again reconnect, install a new spark plug ( by now you have probably gas fouled this one) and refill with fresh gas mix You should be good to go
