As you are still under warranty, best to have a servicing Honda dealer inspect the mower and determine the actual, root problem for the hard starting. Honda issued a Service Bulletin for a defective autochoke and your mower's serial number is in the range of mower that may be affected.
Not all mowers in the range have a defective autochoke, nor can I say your mower for sure
is having an autochoke problem. But, it is something that should be looked at first when there is a hard starting problem.
If it is found to be a factory defect, it will generally be repaired at no charge.
If the actual problem is
not a factory defect (for example, old stale fuel, clogged air cleaner, etc.) the dealer can still make repairs, but at your expense. Be sure to authorize any repairs
before any work is done on your mower.
