A little more information on the engine, or a photo would help.
If you have one of the "push to prime" bulbs on the engine, and the machine isn't very old, I'd expect that you may need to replace the carb diaphragm as they do wear out.
When you say you have cleaned the carb, did you strip it of the fuel tank (assuming it's one of the above mentioned carbs) and clean out the fuel pick up pipe? It has a very fine gauze on the end and is susceptible to blocking up.
