started on the valves today, and, as this guy says, throw those silly suction cap sticks away. I could not get a cup to stick no matter what I did, including the belt stick spray I have used on the rideon. I figured myself to use a drill, and I went about the same speed. what I did not do was the fast one to spread the paste before reversing the direction.
whilst you can remove the valve springs manually, I think the puller was useful. those two little plugs are tricky.
