Drove the carbed 3100 today, ran it up to 6,500 rpm and it was still spinning free and pulling strong, it starts running really well at about 3,500 rpm and seems to just want to keep going up. Does anyone know if the tach reads linier up past the markings at 6,500, say up to 7,500 rpm or so? I don't want to turn it any higher unless I know what it is really turning. Larry
