Thanks, Apinjunkie, for the picture.
My buddy was right, I did not have the full range of flipper motion. At this point, after some troubleshooting, I’m blaming it on the coil stops. The flipper kit I ordered from Pinball Resource was supposed to have the shortest coil stop (8.4mm) but, we agree, we’ve both seen shorter (he’s been teching for 40 years) He is borrowing my game because it’s his wife’s absolute favorite game and today is her birthday so he really wanted it dialed in right. (I.e. easier ramp shot )
He didn’t have shorter coil stops on hand and my stash is at my shop far away so he made up for it by removing the rubber bumper the flipper pawl rests against (also included in the PBR rebuild kit), 3D printing and installing one half as thick, and resetting the flipper rest position and now it matches your range. A 1.5 mm difference in bumper thickness made a huge difference.
If anyone is interested, according to the Pinball Resource, flipper coil stops that work in our mechanisms have the following height:
A10821 (Short) .330 (8.4mm)
A12111 (Med) .370 (9.4 mm)
A12390 (Tall). .420 (10.7 mm)
I’m hoping I have some shorter than 8.4 mm, if not, maybe try shorter flipper plungers?
