It did not want to loosen up. A 300 pound guy with a 20 pound maul and a 4 foot crow bar for half an hour did the trick. Sad part is the liner should have come out with it- and didn't. But there is never no hope. My experience - besides this one- is rusted up valve stems. Even taking the head off is easier than this was. Good luck.   [Reply]  [No Email]

If stuck because it did not have the exhaust covered then not likely to be freed up with out opening it up. That said I buy most of the tractor I have had with locked up engines. I fill the cylinders with ATF put the plug back in and then pour ATF down the exhaust pipe till it starts dripping out some place and let it sit. I then put a 12 volt battery in and 2 or 3 times a day stop by and hit the starter button and watch the crank pulley. If it moves any at all I pull the plugs and try it a few more times. Never just hold the button but use short fast taps on it. I have freed up more then 20 that way and only opened up 2 or 3 because they did not free up   [Reply]  [No Email]
