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.  

Since the EPA forces all engines used in the states to run very lean because of their regulations you are probably fine with the larger jet.  As mentioned above run the engine under a load for a while pull the spark plug and see what it looks like.   There are many pictures on the web of what the plug on a properly jetted engine  should look like.
