..I took this apart and noticed it has a little clashing/rubbing between the two pieces...it doesn't look like it has done this a lot... but...since i am new to this motor, i just need some better advice......i had someone to tell me this was becasue of a weak spring or weak springs....the clutch housing has spider cracks....is this normal....should i replace the clutch spring...the whole clutch....thanks for your support.
