I cleaned out my long fuel pump which was full of varnish from sitting in a garage with evaporated gasoline for 30 years, and decided to take the top cover off of the Bosch motor. When I took the two nuts off the two long shafts, and then took the moor cover off, I found two small springs about 5mm long dropped out. I don't have any idea where these two springs were located. Anyone have any idea?
