Hello. After stripping and repairing my FL 6 lamp, fitting all new seals etc. I had to leave it at this stage do to some health problems. Now restarting. I have a couple of questions to ask you experts. First the spring on the pump shaft. Mine just has two turns, is that the norm?. Second has anyone bought one of these and if so any good.
