I'm having problems getting my belt to sit higher on the secondary clutch. I have the set screw in as far as it will go, and still the belt won't sit higher. I have also tried pulling the set screw out real far too, and same result. From what I understand, the belt should be sitting 1/8" higher than the sheath? Correct me if I'm wrong. Please let me know if there is anything I can do? Something wrong with secondary? Primary? Thanks!
