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):

  • • drain tank and carb then replace with fresh fuel;
  • • better yet, pulldown, dis-assemble and clean the internal parts of the carb.

It would be to our advantage to soak first all metal parts of the carb in a cleaning solution. The idea is to remove the dried fuel residue particularly the varnish like coating/film that may have developed. In some instances, it may be necessary to carefully/cautiously clean the jets with a special tool for this purpose.

Thereafter, attempt to start again with throttle partially open. Then proposed secondary checks (also if have not been done) :

  • • carefully remove the sparkplug;
  • • check the burn color of the ceramic at the tip end;
  • • results would indicate:
  • - if black/sooty, then rich and/or vacuum leak issue;
  • - if oily, then an internal engine problem;
  • - if very light brown to whitish, then lean and/or an air leak concern;
  • • check if the tip is wet with fuel; and then
  • • cautiously perform a spark test;
  • • results would indicate:
  • - if not wet or overly wet, then fuel delivery issue;
  • - if no/weak spark then electrical/ignition concern;
  • • consider replacing the sparkplug(s) (even if new and just for purposes of eliminating as suspect(s).
