My leaf blower wouldn't start yesterday, so I figured it was time for
a carb rebuild - no biggie.

Rebuilt the carb this morning and it still wouldn't start. Pulled the
plug to see if I was getting vapor in the cylinders - yep. Had plenty
of spark so that wasn't an issue.

Then I got to thinking - vapor in the cylinder, spark - WTH?

Then I noticed a wasp buzzing around the muffler.

NO WAY.

Sure enough - some mud wasps invaded the muffler and plugged
everything up good and tight.

Never had that happen before.
