The lock ramp on my HS2 is slow to lift when you shoot the right orbit for RPM and the ball hangs up under the ramp. it has all been taken apart and cleaned , action is good on it in test it does lift and drop just not fast enough in game play, any thoughts on this? oh also found a double switch closure, the top left and right orbit switches also fire opto 1???? I have isolated it to the playfield and replaced the LM339s on the opto board but no dice. any help with this is appreciated.
