Mike,
If someone changed the top links to put it on a *82, then they may have changed the pulley to accept the 5/8" belt as well.
Also, I think the pulley would need to be adjusted along the shaft for a QL vs a *82. It might be worth a look to see what pulley you have and how it aligns with the PTO pulley. Of course, everything may be set for the 1650, since the top links are upside down.
I just ordered a smaller diameter pulley for my QA36A Snowthrower. I hope to see how it works if I speed it up a little bit.
