well went to take the Tejon out and just could not get it to ground Balance well and seemed to just want to false no matter what . its always had a coil cover on it I am pretty sure as there are no scuff marks what so ever on it took the cover off when I got home and found this . guess I will send it in to Tesoro and see if they can fix it for me . in the mean time guess I will have to use the 5.75 coil on it.
