The carb will almost always stick after sitting for long periods of time, few drops of after run oil in the cylinder a fresh plug and they should start right up.

A few months back I was in the same exact boat you are in. Except instead of busting out what I have sitting in the basement i bought a Parkzone electric but went with the 6 chanel spektrum and a BNF. After a couple trips to the field the nitro planes were back up and running, and slowly converting the FM to the 2.4. The electric is nice to get back into the hobby and easy for making a quick flight two in the evening.
