: : : try using #2 FUEL oil it is the same oil you would burn in your home furnace.take your spark plugs out fill the cylinders full and fill your crankcase full to,and let it set when ever you walk by the engine try to give a turn by the flywheel or by putting a wrench on the end of the crankshaft be careful this way takes time.I have had good luck with this.my dad showed it to me .I
: : when all else fails and you dont want to try to dissasemble the engine, try this. take a spark plug, tear it apart, and save only the threads going into the cylinder head. braze or weld a grease fitting to the disassembled plug and put it in one of the two pistons close to the top. start using your grease gun and fill it until i gets tight. DONT GET IMPATIENT HERE. take your time. it may take a few days, but remember, those pistons may have been stuck for years. this will work if properly implemented and without disassembly of the engine. however, if this drastic measure is necessary, the cylinder wall and rings arent gonna be in much shape anyhow. regards and good luck, grapeape

: Make sure that the piston was on the compression stroke, not on the exhaust or your grease will go out the exhaust valve!!! I have had engines with aluminum pistons so bad that none of the usual reciepes will work. It's a good idea to remove the crankshaft when you're using the grease gun method. If you have more than one piston stuck, you'll be applying a lot of stress to the crank journals and connecting rods if you leave them hooked up. As previously stated, it is important to make sure that both valves are closed on the cylinder that you're working on. The easiest way to make sure of that is to pull the rocker arms so the springs can close the valves, assuming the valves aren't stuck too.
