Hi Jason,

I'm assuming its the WMS IJ?

Depends on how long you've had the machine and whether it was fully shopped previously (inc flipper kits).

Whenever I get a new machine (new for me that is) I always rebuild the flippers with a full flipper kit from either RTBB or PinballSpareParts.  I also replace the nylon bushes (important).
The coil should be OK (test with a DMM if you have one)- game off and unplugged of course) and new coil sleeves go with the flipper kits.

If they have been replaced not so long ago - it may be that the EOS needs adjustment.

Best of luck.
