Probably do the same for 2 days or so, while trying to turn it over each day. I know some of the other people on here have their own way of doing it. Maybe they'll chime in later. Good luck. John

Fill up the cylinders and wait a while. Try it every couple days. Soon you will be running again. Good luck!! | | |

Used PB and in a few days it was moving, but only about 45 degrees. It had water (gallon or so) in the crankcase so it is tough to get. I started filling the crank case with all my used oil and ATF (used cause the engine is probablly bad) and plan to fill it to the top and let it sit for quite a while to see if it will loosen up.
There is no mechanical problem so difficult that it can not be overcome by brute force and ignorance.
