OK, so #3 intake is stuck open; not even close to the end of the world. The rapping noise is the lifter coming up smacking it. The cure is starting the engine and letting it run on a high idle. I'd probably add a quart of oil to your tank of gas and turn it into the equivalent of two-stroke mix. There is an excellent chance after a while as the engine gets hot and with the lifter smacking it from the bottom the valve will let loose and come down. Just had this on a '53 I started that had not run since 1976.

#4 is not firing as it shares the intake port with #3 and the flow in and out of 3 is spoiling its mixture.
