I usually wash down the sludge with kerosene and a parts cleaner brush. Spray it on with a spray bottle. Then pour more to flush it down and out the drain plug. Those levers break because the cables are stiff. I take those cables off and soak them in my old oil barrel and then work the cables in and out. Wipe them down with some lacquer thinner and smooth as silk. No more busted levers. Barry
