Quote: The air compressor trick is needlessly complex and risky - if any part of the chain fails, you've dropped a valve. The rope trick works just as well and is more reliable - feed some rope into the spark plug hole, turn the crank until it stops, etc. I did both sides of my engine this way with no trouble.
Valid point! I did some valve work on a motor once...I'd hate to think what would have happened if the hose on the air compressor blew apart when I had the springs off!
