I donít know why but I was thinking the other day that these little generators in order to be allowed in US National parks have to have a spark arrestor, a little internet
search and yes of course they do, and they are exactly like all others, a fine screen
in the muffler
that needs to be cleaned or the backpressure will be bad for the motor
Well on the Honda
you remove the plastic cover to access the muffler
, the three mounting bolts to remove the muffler and the screen
sits just inside of the muffler. Honda
recommends I believe a 100 cleaning
interval, you can either use a wire brush or a propane
torch and just burn off the carbon. Mine had 800 hours on it and seemed to be clean, but I had been noticing lately a different exhaust
note that would come and go, I assume that was carbon being caught and burned off.
Anyway I just removed mine, it just sits in there, and there was no increase in noise
that I could detect.
So if you have a Honda and I assume any other portable generator
you may want to inspect / clean or remove the spark arrestor.
