wrong end of the shaft.
if you look at the pic I posted, on the right hand side where the motor is mounted, to the very left of the motor you will see a large diameter v belt pulley, it is mounted but only free wheels, to the very left and bottom of the v belt pulley is a small chain sprocket which is on the end of the speed advancement shaft.
What I circled in red on the right hand side is the area I am needing some insight on.
Like I said it can't be too complicated, it was made for beekeepers after all.
Sorry the pic I posted is not very clear, I did not take it.
