hello friend you should see if current comes to the ignition coil, then you take out a spark plug you connect it to the cable, leave it macerated from the hub or cylinder cover and hit it a starter if blue spark is fine and if it does not spark and See what layers the coil does not serve or has a reddish orange sparkle, the condenser is ruined. But if the spark is correct, you would like the fuel not to reach the carburetor and woe to the filter or disconnect the fuel filter to see if it arrives. or lastly if it has a spark and gasoline arrives, the carburetor is probably dirty or clogged. That is why it is advisable not to leave much time without leaving. Greetings .
