While replacing tires on my MTH GN engine I encountered a strange happening. While taking off the screw to loosen the driving rod, it was hard to turn out the screw. When it did wind out, the screw was not threaded. What had apparently had happened is the sleeve came out with the screw still attached. Has anyone else had this problem, and what did you do to extract just the screw the next time? For now, I was able to tap down the sleeve and all seems tight, but this is not going to do forever. Look forward to replies. Thanks,
Jeff
