The apparent cause of overheating might be a lack of fuel, but the root cause would be something like a dirty carburetor. The cure wouldn't be to increase fuel flow.. the cure would be to clean the carburetor.
If the carb is truely clean and reassembled properly it won't have the kind of problem you describe.
Describe as best you can what was the result of the engine overheating? and exactly what happened during that time?
