Since you do not know when the last time it ran - pull the plug and squirt a little 2 stroke oil in the cylinder - it could be really dry in there and you do not want to seize the engine
Also, I would run the oil to fuel ratio a little rich as well
While you are pulling plugs - replace it!
Spray a little CRC on all the throttle connections, springs and what not as well - then work them by hand to make sure the move easily and smoothly
Make sure you have water hooked up to the intakes
Then start pulling - it it does not start (or at least pop or sputter) check and make sure you have spark.
DO NOT USE starting fluid - use your normal gas in a syringe if you want to give it shot through the mouth of the carb
