OK so I'm stumped here. I have an Elvis that I'm convinced has a weaker lower left flipper than the right one. Not my first rodeo. The usual fixes didn't work. Flipper assembly is clean, new sleeve, moves freely just like the other. EOS is properly gapped. Then I went further, replacing cabinet flipper switch, EOS switch, coil stop & when that didn't help I even installed a new coil (of course same coil as the right). No improvement.
I've even noticed that the left flipper "gives" more easily when in the up position & a ball comes down to hit it & backhands are weak. I can make the ramp shot with that flipper, but it has to be clean & it doesn't zip up the ramp like the right flipper sends it. So I don't think I'm crazy. Also I've inspected the upper left flipper coil, changed sleeve on that. All is good & that seems plenty strong. What else is there to check?
Is it possible anything on the boards or in the wiring could make a flipper somewhat weaker?
