This 1972 Ski Doo T'NT 400 F/A engine is in good shape with approx. 110 psi of compression per cylinder and strong spark.It has been stored indoors for the last 40 years and will probably run with maybe a couple carb diaphragm kits or minor tune-up work. There is some scoring visible on the sides of the pistons, but the engine has fairly even compression on both cylinders and turns very smoothly. This would be an awesome engine for a race sled, show sled, or vintage rider and could be used in other models as well.
