My brother has been dinking around with an old vintage mini hydro motor he found. I think it's a Mark 55, but the front cover says Merc 650. It has the racing carbs, tiny "flywheel", and I think a D type lower. It has great compression and spark, and as soon as we can set the magneto up properly it should run. I really want to hear it! Can anybody shed any more light on the subject, or tell us how to set up the mag? Thanks!
