Run a cylinder balance test. Loosen the spark plug wires, and with engine idling remove one spark plug wire at a time. Engine should continue to run. If not and it dies when one wire is removed, the opposite cylinder is not firing. Check it for spark and compression, If it has spark and compression and is not firing, check the valve action. Pushrod may be off.
