The engine was rebuilt but is frozen. I have tried every addative to get it unstuck. Question: Could the pistons or valves be hitting somewhere? what could cause it to stick so solid? I have not pulled it apart yet waiting to get it unstuck,(the original owner who overhauled it is dead.) Does anyone have any clue as to where it may be stuck? | | | |
