Ah yes, I completely accept what you say about the tell-tale signs that the unit has not been fitted before. Strange though that is should have been passed around, from hand to hand, in the manner you describe.
Peter Swain is certainly someone I would trust to have had plenty of experience with the Lingo 4, both fitting and use. However, the idea that the motor requires 50 to 60 hours running-in time concerns me as this suggests poor tolerances and/or quality control. A motor like this shouldn’t require any running-in and is really a very simple construct. Irrespective of the validity, or not, of running this motor in you say you have already had it running for 150 hours and the problem persists; on this basis I think it is fair to say it is faulty.
