I have twin post 3stage telescoping jacks on a 150fpm car the job is a 3 stop fairly tall floors. The problem I have is the car has about 4 seconds of stabilized leveling running between floors 1 and 2 good but from Floors 2 to 3 that time increases to about 8. If I run the car from 1-3 I get 4 seconds of stabilized leveling. So for some reason on a One floor run from 2 to 3 my stabilized leveling time is increasing??? Any ideas what might cause this? I have looked for gaps on my slow down magnets they all look good?
