Sometimes, a good fuel system clean can solve it. In the worst case, a complete cleaning of the fuel system / carburetor is required. Typically, poor running due to a fuel deterioration issue is not considered a factory defect so isn't covered under warranty. A Honda dealer can still repair it, but at your expense. If you want to DIY, it is not too difficult; a few hand tools, and take your time. Here are a couple of pages from the shop manual; use a good quality carb cleaner a lots of compressed air to clean all the passages...
Caveat: I work for Honda, but the preceding is my opinion alone.
This engine is only about a month old. Oldest gas would be 2 weeks and all I run is super 93 octane. I could understand if I had fuel that was a month or more old - but that's not the case. If Honda wants to charge me on this, I'll be moving to another brand plain and simple.
