Solved Tracking with Losmandy HQ motor kit

I am still seeing tracking rate that caused G11 mount to advance much quicker than sidereal rate. You have confirmed 1 minute for the pinon of motor to make one rotation. I confirm I have installed HQ 1440 Mount Configuration and appropriate 6.4.0 firmware. I measure the large gear turning the shaft (UNDER LOAD) to the worm turning at nominally 2 minutes as measured by tape strip and visual observation. This rotation is consistent over multiple worm cycles.
IS TWO MINUTES what I should be seeing?

I have tried reserving RA and get somewhat less drift in opposite direction. the drift is worse than no tracking at all. If I can confirm 2 minutes is correct and that variation less than a second could not explain such dramatic observation error I will confine my investigation to the mount itself. I have observed same performance east and West of pier. Thanks!
