It's definetly a problem with your idle. Here is how to tell if it is to lean:

With the glow starter on, reduce it to idle. If it still runs or runs alot slower than before, your idle is to rich. If not, it is to lean. Adjust accordingly.

Remember, turning clockwise is leaner, counter-clockwise is richer, just incase you weren't sure. Good luck and let me know how it turns out.
