Working on both LW3 and TFTC. On both top 2 bumpers work pretty well on both the bottom one is very sluggish. Ball has to hit just right. I took off the switches and spoons and cleaned them up on all. seemed to help a bunch. Are DE bumpers just not as strong as BW?? Any way to make them just crank?? Thanks in advance!!!

I replaced the spoons and springs with Williams springs and spoons when I rebuilt my Jurassic park. that helped quite a bit with the bumper action. They are still sluggish compared to Williams bumpers of the same period and definitely more so that modern Sterns. Make sure the big ass blue plastic bumper body assembly is tight and not cracked where it is fastened to the playfield. I left the coils as is.

I agree with Chet about checking the blue housings? I have found that they are brittle and crack.

The pops can be dialed into a point where they work pretty well, but not quite to a B/W level, or to even that of newer Sterns.

Is it possible to slightly lower the height of the actual pop bumper ring so that it has a shorter up/down travel?
