This is a VERY hard to find original Bosch ZU4 4-cylinder base mount magneto. It was used on some of the Hart Parr tractors and portable engines and probably had other 4-cylinder applications like Crossmotor Case tractors and some early cars and trucks. It is in great shape with no cracks, breaks, or repairs that I can see or know of. It is clockwise rotation and the impulse works as it should. It turns over very nicely and seems to have very little wear in the bearings or the impulse. Everything seems to work as it should. It has good magnetism and puts out a nice blue spark on all four leadouts. Everything inside the points cover looks to be in great shape. It mounts on a 2 inch square bolt pattern and the mounting threads are in great shape. These original ZU4 magnetos are almost impossible to find in the wild or even at swap meets so if you’ve been looking for one for an authentic restoration here’s a really nice one. Let the pictures be your guide. I can be reached at 262 573 1931 if you’d like to talk about it.
