Mikebob, there should be a strike lifting lever inside the movement that your star cam will lift. By carefully bending the lifting lever you can adjust when it strikes. There are some different configurations of lifting levers, the bend can be up the arm a bit so you dont break the end, it sounds like you need to bend it away from the star cam, but as always think it thru before bending, and then there are no excuses for being late
