Clean out the carb. It sounds like you have some small bit of gunk inside the needle valve. Use an aair compressor or one of those cans of compressed air to blow it out, and a little lacquer thinner or alcohol to clean it off.

Gabe,
Fuel for that engine should be ~10% nitro, 25%-28% all or mostly castor oil lube. If you need to buy fuel for it, make it all castor lube. If you run 1/2A fuel in it, you probably won't have it for very long.
