I just did the oil change and bleeding .I'd like to add some to bleed procedure that i found in this webside .while turn the pump do it slow and watch for oil come out ,it have to come out some but you don't want to buy another bottle like me .On the final bleed procedure that require to run the lawnmower again the wall ,I could do samething by hook up a cordless drill to drive shaft and use sand paper on final shaft,the shaft need to clean some rust out anyway
