I am about to replace the coil on the upper right flipper. This flipper sticks all the time and I am getting frustrated. I did many adjustments and I changed the spring and it still sticks. I bought a switch but I see there is not one on this flipper, might make sense because the right button controls the top and bottom flippers - is that correct? any suggestions? The manual is calling out a switch that I can see though!

Yes, it can stay stuck after end of a game. I turn it back on it will stay stuck until I hit the left flipper. When I hit the left flipper button it will release. It sticks all the time, so much I do not even play the game much.

Yes, it will stay in the stuck position when turned off.

Well, you are right, it was not the coil. I bought one so I put it in. Same result. I cleaned everything and the plunger is very loose and when I move it by hand it seems to be clear and moves freely. I agree something is binding but I do not know what. The spring washer is there also.

The only thing that I see is that the coil stop is loose. The end brass button moves in and out about 1/32 and the left flipper which occasionally sticks does the same. The bottom right flipper is tight and I have no issues with that. Is this a possible cause?

The flipper bushing was cupped. Is that suppose to be like that? I am pretty handy with Williams pins but not so much with Stern at the moment.

Great, I think that is it now also. I will post when I get new ones for everyones else's benefit. Thank you very much.

That was it. I had some weld putty and figured I will try that to test it until I get a coil stop. Worked great. Thank you for everyone helping me on this. I appreciate it.
