Picked up a Jokerz this weekend that was missing the plastic that goes on top the center ramp to keep air balls from hitting the glass. So i went to Lowes and got some lexan and cut it to match (the best i could) the original piece based on pictures online and installed it. Now about 30% of the time, if i hit that center ramp with any force, it "snubbs" the ball and sends it back down the drawbridge onto the PF (and drains it lots of times). Am i missing something? Is the original piece domes or something to keep this from happening? My flippers are weak, and I'll be rebuilding them this weekend, so I'm afraid with proper flippers it's gonna happen more often.
Does it do this with the factory piece installed? Does anyone have a good picture of that piece to see if i formed it wrong or something?
