Okay I read the new sticky and it didn't have any info to help my problem. So here it is. Okay at christmas time i had put a new barnett dirt digger clutch on my fourwheeler. It was all installed properly. I had put it all back together and have never been able to get it to catch. I do run yamahalube 4 oil so that shouldn't be the problem. I have enough oil so that also shouldn't be the problem. Now my springs I got with the clutch so they shouldn't be worn and none are binding. The little hub the springs sit on is put on right. I just can't figure it out. Could they be glazed? Should I try roughing them up? Is there a break-in procedure. Please get back to me I'm stuck. Also I would like to add that today when I went riding they caught well for awhile and then started slipping.
