Turntable weight affects speed

I tried a Thorens tt weight on my Thorens TD-850 belt-drive tt. It noticeably slowed it down.  It seems like extra weight on the bearing would affect any tt, but what do I know?  Is a speed control (and strobe/test pattern) generally required to use a turntable weight while maintaining the proper speed?

It just may not have the power to haul the extra weight. Is the belt clean / new? Have you tried giving the platter a hand in spinning up to speed?

But aren't you just increasing the speed (power to the motor?) to compensate for the additional load? I wonder if that will overdrive/overheat the motor and impact its longevity.
