I have a 1978 motor in my It 400. I've been searching the internet without much success, how to check if the reed valve is operating properly. Does any one have experience in this field?

Why? Reed valves are normally fine forever pretty much. Metal ones can loose their flexibility over time. The fiber versions as a rule so long as they are in good condition. As in not split or cracked are generally ok. The ones in my DT are over 20 years old.
