Hi Dart
Someone else who understands the difference that elevation makes to a non adjustable carburetor. If you ever took any flight training, that's one of the first things you learn when climbing to altitude. Here's what I've been able to find for the Honda engine on the lawnmower in question (Honda part numbers).
P/N 99101-124-0680 # 68 jet for sea level to 3,000 feet
P/N 99101-124-0650 # 65 jet for 3,000 to 6,000 feet ASL
P/N 99101-124-0620 # 62 jet for 6,000 feet ASL and over
Hope this points you in the right direction,
Sky
