I read a book in the early 70’s. It was about a teen boy and his misadventures in a small town. It had a cover with a kids driving and old blue jalopy In the book. In One of the stories he gets a commercial propeller and puts it on a car to make a go faster. It flies loose and goes flying through the town, destroying things. I think the book had a white hardback cover, and the picture of the boy in the car was like light blue drawing I think it may have been a Scholastic book. But it was about this young early teen boys misadventures. And I recall the propeller wrecking havoc story. The book may have been from the 60s. But I read it in the early 70s. It may have been one of my older siblings book. And it probably was from the Scholastic catalog.
