you will need 2 (2ft or so) small chains from your engine hoist. Hook 1 with the center of the chain on the hoist and each end hanging down. Slide one end over exhaust stud on the #1 cyl, and one over an exhaust stud on the #4 cylinder. Screw the nut back on, with a big enough washer to not let the chain come off. For the other side of the engine (carb side) get a long, (6" or so) 3/8" bolt. Slide it through the "handle" on the engine case and attach the chain. Again, use a washer that will not allow the chain to come off.
Take it easy when lifting and make sure you are not snagged on anything. I have done this several dozen times, and never had an issue. Just be careful and go slow to make sure everything is secure. If you don't have an engine stand, use an old tire and set the motor in the center of it.
