RE: adjusting draw weight on hoyt bow
Yes, if you have your bow tiller tuned and then change draw weight unequally on either limb bolt, you mess with tiller. This also changes the nocking point height.
The easiest and best way to assure even tiller is to bottom both limbs out as heavy as they will go, and then back them off equally until you reach your desired draw weight.
Im 99% positive that QT undid the limb/riser connection. Hopefully no damage was done to the smaller set screws inside, and it can be torqued to spec. Have a pro-shop look it over though, other wise you may have problems. Nothing major really, but it will definitely cause inaccuracy.
