That's the only paid tech I actually know. I do all my own work so..

*edit* Paying an awful lot of money for a really easy fix if all you need is a flipper rebuild. Just saying.

Perhaps loose set screw?

Sounds like it's just loose in the pawl/crank. There's usually like two set screws/hex nuts (depends on the era...the hex nuts are usually newer stuff.) that keep the flipper shaft engaged with the crank.

Manual is here: http://www.ipdb.org/machine.cgi?id=362

Page 20, you'll see it marked "lever arm assembly". And there's a ( (.) ) shaped circle with two things sticking out in a Y position from the center...those are the set screws. If you can rotate the flipper in the pawl while holding the solenoid plunger still, it's loose. You just need to set the flipper to the correct angle and tighten those screws. You want the plunger and linkage to be fully extended when you do this, and for there to be a 1mm gap or so between the assembly and the plastic bushing that goes through the playfield when it's tight. You want a tiny bit of play in the mech to keep it from binding up!

And don't forget. Turn the power off FIRST.

Yes. Unplug game. Unlock the coin door. There will be a lever on the top side of the coin door inside the cabinet that will either slide right to left, or flip down, to release the lockdown bar. Take off the lockdown bar, slide the glass out. Remove the ball (Single ball em, you can usually just nudge it from the drain into the shooter lane with your finger. Playfield rests on a metal bar by two metal brackets. You can lift up from the apron/arch above the drain hole by the flippers, in most cases to raise it. Shouldn't take a lot. Some games might need a nudge from underneath, especially if they've been sitting a long time.

There will likely be some kind of prop bar or rod in the right side of the cabinet that is meant to rest the playfield at ~30 degree upward angle or so, but frankly...those things suck, and most people just lift it up all the way and rest it against the head. You may have to slide it forward towards you a little bit to do that, and back in when you lower it. None of this should take a large amount of force. If something feels stuck...it is, and you might have to lift up the back of the playfield to slide it a little, etc. Most EM games don't have any protection against pulling it out too far and dropping it in the front of the cabinet, so can be wary of that.

There's another option....which....is not exactly kosher, and I'm sure someone will tell me I'm an idiot for doing this, but I do it anyways..... which is to rest the flipper mech brackets on the lockdown bar reciever. Risk is you potentially bend the coil brackets, or pull out the screws from the wood if you mess it up badly, and it's not as secure as having the playfield up against the head. The only time I really do that is when I'm making quick little adjustments like changing a flipper out. Modern games have rails and pegs that makes servicing a little bit easier. =\

*edit* Oh, and don't set the glass down on a hard floor. Use a folded towel if you need to. Tempered glass (it SHOULD be...it might not be with EMs...) doesn't like contacting hard things on the edges or sudden temperature changes.
