Welcome aboard, Diego!
The first thing to do is pull the spark plugs and see if they're fouled. This is quite common if the engine is idled for long periods of time. While you have them out, it would be a good idea to perform a compression test. Make sure you ground the spark plug wires and open the throttles.
