I bought a FW in an estate acution a few years ago and have just had it serviced and started useing the last 2 weeks. You can see other post to see why I am useing it. My question is: Sometimes when I press the foot peddle I must turn the wheel to get it started. It has a new belt and it is not slipping. Is this normal for an old FW? I know sometime I must turn my wheel to get me started. But like the FW not everytime.
