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 checks (if have not been tried):

  • • attempt to start again with the throttle wide open and then carefully remove the sparkplug again to check if it gets wet with fuel;
  • • if able, temporarily remove the air box (housing) and cover the throttle body opening with the palm of your hand while attempting to start to determine if there is suction and if your palm would get wet with fuel;
  • • perform a compression test or better yet, a leak-down test.

Please post back results / observations of the above once tried.
