os Wankel 1800
Hi there! I am trying to find out what kind of screw fits the rear side of the old style(1800) OS Wankel. I am talking about the screw that holds the counterweight in place. I think it is a counter rotating screw(i.e. you turn it counterclockwise to fasten it) but I would like to know the specs, so I can have a new one made. I was unable to order it from OS, the one they now provide is for the newer style engine(1801). Can anybody help me, or advise what to do? Thanks, and kind regards, Mick
