Hi martin and thank you for your answer. There is fuel coming to the engine. The starter cranks, but i think there is no spark. I have removed the spark plugs and they have the top covered of black shoot. I'm afraid i could have flooded the engine when trying to make it start, by pushing the throttle maybe too much and various attempts. I'm going to try changing them. By the way, i forgot to mention that the first time after the carb rebuild, the car started, after three attempts (i think because off the empty carb bowl and a weak battery...) but as soon as i stopped pushing the gas, it died. didn't held the idle. So i turned in a little the idle speed screw, and since that the car won't start anymore.
