Converse, I have no idea, never had one and not interested in them because of the problems. I believe when they are running they are smoother but at the end of the day they still only cut grass. There is one on Ebay or Gumtree at the moment, they are only for collectors who must have one, nothing wrong with that, people would clamber all over an Edsel or a P76 if it came on the market these days.
I also saw a half brother of the twin for sale, it is the 85cc version, I think that one was on Ebay
