Replacing nuts with screws didn't work for me. I took 70 winds off the coil,and still only getting 2/3 over center lane from skull lock.I started building up end of ramp to try for more air and it worked 3 times(9 balls) in a row while manipulating it,but during game play it was only about 80%. I have a plastic protector over the blob plastic,so I'm gonna take that off to see if that's the culprit.
If that does the trick I think trying to raise the ramp angle a little more to clear the double layered Blob plastic should work.
I won't settle for anything less than 100% on this as I feel it is important the balls land in the pop bumper area . One popping out straight down the middle is just unacceptable when trying to hit a Jackpot,but cracking a hard to get Blob plastic by leaving the protector off isn't wise either.
