Quoted from Schamattack:
Any one have issues getting the ball to shoot up the side ramp? I think my spring is weak on the plunger. I adjusted it to make sure it was straight. The auto launcher gets up no problem and if I smash the knob is launches up no problem, only if I pull the plunger back and release it struggles to get up the ramp. Any input would be appreciated.
My auto launch doesn't hit the ball hard enough to get it up the left ramp, don't think it's supposed to.
You might want to check the manual and your auto launch coil to see that the correct one is installed.
As for the manual shot making it up the left ramp, I bought a stronger spring. The standard spring (10-148-1) wasn't strong enough, so I put in a red 10-148-2 spring.
