OK... I MAY have found a good solution to the auto launch issue. I've tried all of the 'solutions' and so far have had the best success with this.
A shooter lane cleaning and wax or wipedown with "Wizards Mist and Shine" will result in almost 100% success for the short term and then slowly the auto launch plunger will no longer make it fully around and down to the right flipper. No adjustment to the power setting makes much difference in my case. I've shimmed the shooter lane ramp, secured the outer lane guide, etc... nothing has offered a long term solution so far in my case.
Last weekend I changed out the auto launch coil from a 23/800 to a 23/700 to give just a little extra boost. (remove the diode if new coil has one).
Before changing the coil I was at 0% success as it had been a week since cleaning the shooter lane. I replaced coil, didn't clean shooter lane and I'm now at around 95% success rate for the ball getting all of the way around back to the flipper and I have the auto launch power setting at only 215.
I've played several games including a 1.4 Billion game this week and the success rate is so far staying very very high.
I'll do my normal cleaning this weekend and report back after getting many more games on it this holiday weekend to see if this is in fact a good solution.
