Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I just bought a pressure washer powered by a Honda GCV190 motor.  I bought it at sea level, but recently brought it to 6,200 feet altitude.  It seems to run well at 6,200 feet, but I wonder if I'm either damaging the engine or running the risk of fouling it?

Honda makes a couple of inexpensive (<$10) substitute carburetor jets for higher altitude.  The manual says to bring the unit to a Honda dealer to substitute the alternate carburetor jet. 

I'm wondering if (1) I should bother with switching the jet and, if "yes," (2) whether it's an easy switch that I could perform without hauling the unit back and forth to the dealer?

I'm mechanically inclined and have good tools, but have never done anything beyond minor services (e.g., changing/gap-ing the plug, changing oil, and changing/cleaning air filters) on small engines.  Does anyone have experience making this switch?

Thanks.
