Did some more service to my machine today. Rebuilt the flippers and replaced the flipper coils - one was from a Gottlieb and one was stock, so I just replaced them both. The left flipper is working much better, but the right flipper is worse than before the rebuild! What can I check? I cleaned the flipper button switches and checked that the piston is not catching on the plastic sleeve - there was a different sleeve that came with the rebuild kit (thinner wall) should I use that one instead of the sleeve that comes with the new coils?

Here is some video of what is going on.

Thanks in advance.

The EOS was out of adjustment. In fact, after I changed the switches I didn't know to check the gap - 1/8" or 3.2mm. I adjusted both and now they work great! Thanks for the heads up.

How much up and down movement is normal for a flipper coil? I can't seem to secure it so it doesn't move. There is about a 1/4 of free play (up/down). Is this normal?
