Thought this over and i did a bunch more. Filled one cylinder with oil and put spark plug back in.
I bolted on a old exhaust manifold and put a 6 foot spud bar (steel digging bar) between it and the head. My 11 year old held the end of bar.
It was really tight. A good impact will break it loose but my Campbell Hausfied at 110 psi with a squirt of oil in it would not touch it.
P.S
I picked up with hoist, lowered it to the ground, left hoist attached and it still wanted to roll on ground.
