Well I've done about all I can do and still ain't quite there yet.Has anyone ever ck'ed RPM on a Eska 7.5? Mine seems like it's running about 1/2 to 2/3 open.In the barrel ck'ed w/Tiny Tach--ranges between 3370-3410 rpm.Doesn't that sound slow? Does anyone know what the rpm wot under load should be?thax
