mine has a whack, too, but i still have the arrow just on there. it's about at the edge of where yours broke off, i think. mabey wrong, but i can't go look at it for a few weeks. just adjust the free play in the arm to 1/4 to 3/8 if you do adjust it. you will have to overcome the spring on the arm to feel it, but i don't think you can really release the clutch with your finger but it does tak some pressure to move the spring. you can do the free wheel and put it in gear, or you can warm it up, get it rolling and put it in gear with the clutch pulled. play with the clutch and put around, and rev it a few times with it in gear, clutch pulled. it should start letting go
