I have had some issues with mine sticking in the engaged position.By the way I set the gap at .30 on the install.I used about 1/2 of the shims that I bought separately. The SC Pulley will stay just touching the connection point. If I grab it I can move it back to the correct gap. I did speak to Jerry at eurocharged about this. He asked for pictures ,and commented that it sounding like something was bent in the pulley assembly. I sent the pictures ,and never heard back from him. I just hadn't had time to follow up again.
