CPR star rollover problems

I did 3 things:
Trimmed the holes as directed
Put in trimmed down stars that didn't reach to the ends
Used a very sharp exacto to trim around stars that still stuck after that. I would shave the insert until the star moved freely.

I probably wasted as many stars as I left installed doing a captain fantastic with 8 rollovers

I have not had the opportunity to use a cpr playfield, but in doing some of my own clearing with star rollovers one area that might need to be looked at is circled below, the bottom of the slot around the center. I did not see that addressed in the cpr instructions i found online. I used a fresh Xacto to cut and clear out that area to allow them to fully seat.

A little figured it was less destructive than the insert

You need to get some file files or a dremel with a diamond tip grinder and clean them out. It usually takes me 15 to 20 mins per insert to get them moving properly. The small files are the key.

I cannot understand why they dont put upside down stars in those when applying cc. Would save SO much trouble.
