Redge:
I have a number of "tools" w/ b/s engines, and really haven't had any issues with them. I see there are some 22 ton units out there, one with a Kohler and one with a b/s. Lowes also has a 27 ton unit w/ a honda. All are the horiz/vert models pretty much with the same auto return valves, etc.

Good thing your "incident" didn't get out of hand and you had plenty of beer to cool things off.
