Default Re: Tight engine

Marvel Mystery oil in the cylinders and added to the oil. Hand crank it a few rev's, let it sit a few hours, hand crank it again, let it sit. Do this for a 2-3 days hand cranking it whenever you pass by. I am sure you will notice it loosening up.Then try to start it. If you can remove the valve side plate you might want to squirt some oil/MMO on the lifters also.
Keep us posted.
