In the event that this doesn't solve the problem, the carburetor may need to be removed from the engine for more extensive cleaning. I took it apart and cleaned it out, put a new needle and seat in it and it worked fine in warm weather. All of these conditions are consistent with a gummed/contaminated carburetor and or bad gas. It wouldn't start when I needed it yesterday, and the carburetor seems to be the culprit. Really the carburetor was just pretty gummed up, but since I had it apart to clean, I replaced the float, needle, seat and power value.

Vacuum leaks in the intake system could also result in similar symptoms.
