That's true, but isn't it also true if you run an electric winch on battery power alone (ie, with the motor off) You can drain your battery real fast or you won't have as much power as you would if the motor was running. I'd be kinda leary of running a hydro winch with a carb, I know steep inclines and off camber stuff can screw with Holley carbs, I guess Webers and other carbs are the same.
