- old chicago(all i've got)
I recently did a flipper overhaul on my Old Chicago and they kicked A** afterwards. 2-3 weeks later they seem very "sluggish" and weak. Some of the pop bumpers have lost their umpf also. I changed the coil in the worst one but it made no difference. Any ideas? I'm far from an expert but everything looks ok to me. Where should I start looking?
