Common problem, a little varnish and setting around can cause a little rust, and you get stuck valves. If I smack one with a hammer, I use a rubber mallet. Soak, smack. The last one I had stick, the valve was too far down to soak it, so I tried a trick that I stole from this site. Take out all of the spark plugs and find a way to turn the motor over, BOTH WAYS, so you can rock it back and forth(turning the fan,socket on the crank shaft, etc.) Bring the piston up to the top on that cylinder.you can stick a screw driver in the spark plug hole to tell when you are there. Pull the cylinder up a little and fill the cylinder with a piece of rope,(leave a foot sticking out of the hole)turn the piston back to the top and when it stops the rope should be pushing the valve up from inside. You must take you time, or you can bend the valve and then you have to pull the head. When you get the valve moving even a little bit you can spray more stuff and tap it down with the rubber hammer. The last one I did took three days,every time I walked past I either rolled the motor,tapped the valve and shot my favorite rust buster,acetone and atf,mixed 50-50(BTW it will separate so you need to shake the oil can every time you squirt.

Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
