Cat guy, read all the replies, reply 3 the OP says it has a 100# compression in cylinder 3. That should be enough to make it pickup when the spark is returned to that cylinder. And reply 16 says he reset the valves. Not sure why a guy would look at a thread at all if he doesn’t have time to read all the replies?A valve is your issue probably a bit tight not letting it fire with compression. A compression test on that cylinder would tell you if they are so tight they leak.
OP, a head gasket would have to make an obvious ppsss, ppsss sound on every compression stroke to leak enough not to fire. If it was pushing that much compression in the radiator it would be shoving water out the cap. Wherever you think the pressure is going as I said above with a 100 psi the spark cutout to that cylinder would/should not be noticeable.
