Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, proposed preliminary tries (if have not been done):

  • • attempt to start again;
  • • carefully remove the spark plugs;
  • • check if the spark plugs are getting wet with fuel;
  • • cautiously perform spark test on all 4;
  • • drain each carb separately and collect the fuel from each bowl individually ;
  • • check/compare quantity and quality;
  • • if too little or uneven, check clean the fuel system/fuel path;
  • • check breather and/or evaporative emission control tube (depending on the version).
