To be completely honest, I would seek another TQ ether built and ready to run or a parts carb and give rebuilding it a shot. There not to hard to do, not complex as I think you have been lead to believe. Any carb to be rebuilt should have strict attention to detail. The TQ's biggest area to lat fine attention to is the linkage rods. They must be correctly measured. Then there are the throttle shafts. They should not be worn.
