Back to the flipper issue...I pulled mine apart (T2) for you tonite and took a couple more happy snaps. The spring I was talking about initially are not installed on mine either (are on D.E LAH)..so that is most likely not your issue.
The funny thing is in the process of pulling mine apart and back together, I re-created your problem. THe flipper was quite stiff to move (by hand) and not flowing freely. I suspect if this is the case your coil is getting very hot cause of the load and blowing fuse (assuming your wiring is correct). IF the fuse is blowing whilst your holding the flipper in then I'm off track.
Anyway, I don't know how or what caused mine to bind up, however after putting in back in again (3rd time) everything was fine. I would suggest the following before we go on:
(1) take coil stop off (both hex nuts) and check you have coil sleeve in the correct way.
(2) when putting coil in, make sure the locating lug (not sure of its correct name) is seated in firm in its recess. I put mine in on an angle, so lug when in first, then placed coil stop on rear of coil 1st, then made sure it was square and flush before screwing in. Before you tighten it up, just keep checking the movement by hand as you go in, to make sure its all square..
This worked fine for me and flipper movement is very free.
See attached photos....In case I am off track anyone please correct me!
The one thing I did notice when it was binding up (look at middle photo), there was a bit of an angle between coil stop and back of coil (ie not sitting flat).
