This is a vintage, used MDS .40 nitro fueled aircraft engine. The engine was from an estate and was dried fuel locked-up. It was soaked in clean fuel and the after it was loosened, was spun with a starter, the photos show the subsequent compression gauge readings. The carburetor pinch bolt has been left loose to facilitate packing, by turning the carb. PLEASE NOTE: This is a used engine and is non-returnable.
