Hi and welcome to JustAnswer,

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

Initially and for the "...idles but does not rev up and backfires...", proposed preliminary tries (if have not been done):

  • • ensure battery voltage does not exceed 14.5V even when attempting to rev the engine;
  • • check or better yet, replace the sparkplug;
  • • verify integrity of the sparkplug wire and cap with no arcing;
  • • ensure fuel quality, quantity and delivery.

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