common problem that has actually nothing to do with your supercharger issues. it's a mechanical problem, the link movinh the ramp up and down behind the backpanel sometimes moves too far, gets stuck and prevents the ramp flap to go down again. i solved this problem permanently by securing a small rubber inside the channel of the backpanel, limiting the space the arm of the up and down mechanism can travel.

for all your supercharger needs see this thread

here you go, it's a post rubber in which i chiseled a grove to stay in place. works perfectly, it never came loose and the ramp works flawlessly since i installed it half a year ago. just make sure the ball can pass without touching the rubber.

also tighten the diverter (allen screws on top and bottom<-pic) on the SC to lower your test number and speed up the ball. a loose diverter makes a big difference because the ball looses momentum every round it travels.
think it's hard to reach in without removing the SC, but it's really no big deal, just follow the steps in the thread i posted earlier.
