Pat,
I'll bet a Jack-In-The-Box Ultimate Cheese Burger the hook timing is late.
Put the needle in the center position. Visually verify the needle is in the center of the needle plate slot.
Remove the needle plate, bobbin case, bobbin and presser foot.
Remove the face plate and find the scribed timing marks on the needle bar.
Turn the hand wheel till the needle bar is in it's lowest position. You'll see the top timing mark just at the bottom of the bushing.
Turn it some more until the bottom timing mark is at the bottom of the bushing.
Now, look really carefully ...... the point of the hook should be centered behind the needle.
Is it?
Joe
