My 47 Dodge was brought out of a 10 year storage, I changed the fluids and put some Techron in the gas. It developed a miss on one cylinder, had leak down and popped out the tail pipe at idle. I remembered from years ago that carbon can come off the top of the pistons or the combustion chamber and get stuck in a valve. So I fired it up, it was missing bad, took off the air cleaner and brought the rpms up. Then I slowly trickled water down the carb. Within about 20 seconds the engine started running smooth as silk and the miss was gone. So it had a chunk of carbon stuck on the valve face. I then went back and did a compression check on that cylinder again, all good and the leak down was gone as well. So I got lucky this time..... I always start with the simplest remedy and work my way up to the wrenches if needed. On another engine, Jeep F134 it did have a burnt valve, part of the valve head was missing! So on that one I bought a new valve for $13 bucks, the seat was still perfect, so I hand lapped them to each other with a suction cup tool and lapping compound, put it all back together and it ran great, and still does, that was 4 years ago.
