>>1759292The farther it is from the gears the worse it will shift. It should be positioned so when the outer face of the derailleur is even with the outer ring there's about 3mm clearance.
If it's all the same parts that (presumably) worked when they were new then maybe it's gunked up or rusted or something and can't go all the way out now? Other than that might need to take it to a shop and have someone look at it in person.
