The Honda GX 630, 660 and 690 have the same exact specs, yet different HP ratings. They use different cams or something?
On a side note, would my 630 theoretically power an 8gpm/3000 pump if/when I choose to upgrade? The formula puts it needing almost 22hp, a smidge over what I have.
Gotta be a hotter cam or something. If you look at the HP graph, the 690 is just getting started at 3600 rpm, which makes sense. The 630 levels out at that RPM.
Yeah, I guess it was working harder than mine does washing a house…staying on the trigger a lot more… And, I imagine with washing those large buildings that you are on the trigger a kit more even just washing buildinga…as compared to my house washes.
I am really amazed at how efficient mine is. I was just commenting on it to my wife the other day
Wait really? I guess soft-washing consumes a lot less fuel than higher pressure hot-water washing because I routinely go through 10 gallons or so in a 8-10 hour day washing fleet.
