Are there any difference between idle and high-speed,does the engine run longer at slow speed .<br />Did you remember to open the air vent on the tank ?<br />If not, open it :) .<br />If , maybe time to take a look at your fuel pump and/or fuel line.

It was last year, but I am sure that the air vent on the tank was open an the pump was hard, so i do not think it is the fuel line.<br /><br />how can i see if my fuel pump are not working as i should?<br /><br />Can I have assembled the carb. wrong? what about the float in the carb?

When the engine starts to die, pump the primer bulb and see if it continues to run. This would indicate a fuel pump problem or a carb problem. If you are fairly sure you did the carb. build right, it is probably the pump. Does the primer bulb stay firm when it does run for the 5 minutes or so?
