Hi and welcome to JustAnswer,

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

Initially and since there is spark, then it would appear to be a fuel delivery/starvation issue (most likely) or a combustion chamber problem (least likely). Proposed preliminary tries (if have not been done):

  • • remove the whole air box (not just the filter);
  • • attempt to start again but with your palm covering the carb mouth;
  • - determine if their is strong suction;
  • - check if your palm would get wet with fuel;
  • • consider a compression test or better yet, a leak down test.
