I have a seized engine, I have removed the bolt to the base of the jug and tried to rock it back and forth get it loose, this thing is pretty stuck, I rebolted the jug and I would like to use some kind penetrating oil to free this thing, I was thinking of adding some WD-40 to the cylinder let it soak overnight and trying to use the kickstart to free it. I have hear mystery oil and other oils, If i can get some ideas or suggestions to removing this piston. thank you =)
