Re: looking at getting new to me skoolie....
if they have been sitting a long time, the orifices can be plugged up, and possibly things like connectors in the circuit boards corroded. that is a chance you have to take if something is free. if you can test them before removal it would be best as parts are sometimes more than a good used one that works on cl., and you should always insist on seeing a cl item work before you buy.
