I am wondering if anyone can tell me how to get a engine unstuck. What is the best way to get it to run at the least cost. And how long to you let it sit before trying to start it.

Nick I know you want to unstick the engine as cheaply as you can,the question you need to ask yourself am I going to keep this tractor and use it or sell it. Every stuck engine I've freed up the rings are stuck in the ring slots,just because you get it to turn over the rings are still stuck in ring groves and you know what that spells oil consumpstion and possibly scoreing cylinder walls. I now usually now if I get one that is stuck I unbolt the rods and pull block and pistons at the same time and clean them up and hone cylinders and put in new rings and head gasket and slap it back together which I think is better and cheaper in the long run. Gmans two cents worth

Gman, your two cents is worth a million dollars. That is sound advise & by not pulling a stuck engine apart to free it he risks expensive damage that could easily cost more in the long run....

Done this to 47 A. Remove the spark plugs and fill the cylinders with classic coke. Engine should free up in about 2 weeks.

I would take off the crankcase cover and fill it with diesel fuel, then take the spark plugs out and fill them also. Then forget about it for a week or two. We made an adaptor to screw a air hose in to the spark plug hole. Then put 150lbs of compressed air to it (You will want to remove roker arms and push rods). This is what we have done to most of our tractors. Hope this helps Larry

What Larry said has worked for me too EXCEPT... DO NOT USE COMPRESSED AIR!!! Most times it may be ok but if something breaks, you have what is called an explosion! Make a spark plug adapter to take a grease fitting, then pump in grease (my GM took 7 cartridges) and listen as the grease lubricates the cylinder wall and squishes past the rings and slowly forces the piston down. Of course you have to push on the cylinder with the piston nearer the top for best results. And then it should be taken apart, but just to get it running this sometimes works. Oh, and start it up outdoors!
