I am going to be putting new impeller and housing, and a new thermostat on today and was wondering what is the best way to flush the cooling system on the motor, 3.0 OMC with Cobra drive, raw water system and question #2, I am having rough idle(lumpy) and was wondering if a can of carb cleaner is a good idea and while I check timing what should it be set to with timing light? and one last thing, fuel filters, cant seem to find an inline filter but think i have screens in the carb behind big bolt, any ideas, maybe add inline filter/water seperator?
thanks
