Let it set for a week, then try to rotate the fly wheel or how ever u can rotate the crank, be sure u have oil in ur engine ( 10w30 should be fine, there are many fine oils out there, I use mobile one synthetic, but u probably have ur favorite. I would use only 12 oz of mmo to a 4 qt system. Run it on a test stand if u have one. Saturday I poured 4 oz off mmo into my brake booster line and let it set 30 min. When I started the engine, it smoked for sometime, killed all the skeeters in the yard, smoked real good , then I drove it around the town . I do that from time to time.
