Quoted from MJW:
Mine works some games and other games does not come up at all. Weird.
Not sure if it's the same problem my game had when I got it from the previous owner, but the coil bracket had shifted a bit making it difficult for the post to pop up.
I unscrewed it from the bottom of the pf, took the coil sleeve out to give it a cleaning, and then reassembled and manually popped it up to ensure it was smoothly passing through the hole.
Have had no issues since.
Now just have to figure out what the first grave marker drops down as soon as a game/ball is started. Once the mech fires that markers up, the first one almost always drops.
I replaced the spring with the same part number, but no difference.
I have the replacement marker kit from PBL, so figure if I can't get the old marker to work, maybe replacing it could do the trip.
