According to specs manual timing marks should be at 149 and 65. When i install at 149 the other side is bout 10 degree off. It lines up at bottom of valve opening at about 55 degree. Seems like 130/65 works better but this is definitly a 657x engine. Is there something i am doing wrong. Ive studied the install directions over n over. Any one else seen this before
