I was playing about with pumps on a bare crankcase with just a camshaft fitted recently:
my note to myself says that the best amount of pump eccentric is presented to the lever when the cam for No. 5 valve is pointing up.
I found a lever which if presented to the eccentric in other positions would slip off and jam, but if offered up to maximum eccentric - ie. lobe down, No. 5 cam up,
looked like it would work fine and couldn't slip off when running.
