My 122 don't want to change to slow speed. This is happening on the top rotor only. I've cleaned and oiled the motors. I've adjusted the slow motor, where the shaft hits the rubber 
O-ring, over and over. Still, when I change from fast to slow, most of the time, I have to switch back to fast, then quickly back to slow to get it to slow down. Sometimes I have to do this several times before it will go to slow. The Leslie has an EIS solid state relay in it. I've checked to see if the voltage is correct at the motor outlets when the switch is thrown and it is OK. I haven't changed the O-ring. I thought I bought a spare the last time I got some, but can't seem to locate it now. It's looks OK with some wear, but not too bad.
Looking for something else to try. I'm thinking maybe a motor rebuild with new springs and washers or, maybe I just haven't hit the sweet spot in my adjusting of the slow motor shaft against the O-ring and I need to keep trying that. Any suggestions?
One other thought, I'm going to get a Hamptone Motor Controler for my Leslie 21H so I'll have slow speed. I may get one for the 122 also, and just do away with the slow motors altogether. What are your thoughts on doing that?
 
 Thanks, Ricky
