2 cylinder fuel pump camshaft

[aaronb]

Does anyone have a picture of the camshaft on one of these pumps? I bought a used working takeoff. One of the camshaft lobes has a valley in it. I'm just trying to make sure it's not designed that way. The camshaft doesn't appear to be damaged. I'm just trying to figure out if it's any good or if I should return it. I was going to rebuild it if the camshaft was good. Thanks.
