It was interesting to read the "News Cuttings" articles that Jack posted and of particular interest to me was page 2 where Victa claimed that the twin should be run on a 50:1 fuel mix. My guessing would be that this was a contributing factor in so many of these twins failing early in their life. What was it in the Victa twin design that enabled this motor to require so much less oil in its mix? Any thoughts?
