Quoted from BJM-Maxx:
I got back to playing my Taxi again finally after finally putting it back together. I get such a varying behaviour from the from the plunger it really is annoying me. I spent a lot of time getting it working really well (being able to wrap around the bowl shot so it is really a skill shot), only to find it could barely go around 3-4 times. After playing it for a while it noticeably changed for the better and then got worse again after that. I tried making some alignment changes again and got things working better but the behaviour is constantly drifting.
Is this just the nature of the beast? This is the only machine I have that I have really ever had to give thought to making the plunger work.
That's why you need an MRS in that spinout ramp! That takes some of the variability from the Cherry switch....
