Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, let's review the basics. Proposed preliminary checks (if have not been done):

  • • drain-clean tank and replace with fresh fuel (even if just to eliminate as a suspect);
  • • attempt to start again working the throttle as if trying to flood the engine;
  • • then remove the spark plug:
  • - determine if the tip got wet with fuel;
  • - carefully perform a spark test;
  • • pour a small amount of raw fuel to the spark plug hole;
  • • re-install the new spark plug and attempt to start again;
  • • if still a no-go, drain the carb bowl to check quality and quantity of content.

In most instances and particularly if has been in storage, the carb would have to be pulled down, soaked, cleaned and adjusted.

Perhaps the video HERE can shed insight on the carb pulldown and cleaning.
