i was practicing the other day and i pulled in my clutch and it would not return. i thought that the cable had just broke but when i went to put a new one on it still would not return. i have the pep relocater or whatever where the return lever is on the engine. it came with the quad when i bought it. the quad ran great all day until then and the clutches in it are almost brand new. is there a spring or something inside the engine that may have broken or needs replaced?
