Sorry about that Tammi! No, when I step on the pedal and it doesn't go, there is no motor growl. Just uneasy silence.
And maybe a little cursing under my breath.
I did try some experimenting tonight with the belt. I loosened it quite a bit, but there was a lot of slippage. So I tightened it up again (not quite as tight as before) and it seems to be pretty good. Time will tell! Now that I know how to move the motor about and tighten/loosen the belt I can try different settings to see what works best.
Thanks for the reminder on the grease, too!
