I have a Craftsman LT1000 917.272761 with a stuck freewheel control lever. Pulling the handle at the rear just stretches the spring on the rod, and doesn't move the lever, so I cannot roll the mower manually. I removed the battery and holder, and I can move the lever with a screwdriver, but it is very stiff. I cannot find anything in my searches online to tell me how this lever engages/disengages the trans-axle, where its internal return spring is (I am assuming there is one since the handle only releases the lever to move back into its "drive" position), or how to lubricate the lever pivot to free it up. Please let me know if anyone has advice. Thanks
